    Mode for Carrying Out the Invention



    [0011] Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar elements.

    [0012] As used herein, the expression "have", "may have", "include", or "may include" refers to the existence of a corresponding feature (e.g., numeral, function, operation, or element such as component), and does not exclude one or more additional features.

    [0013] In the present disclosure, the expression "A or B", "at least one of A or/and B", or "one or more of A or/and B" may include all possible combinations of the items listed. For example, the expression "A or B", "at least one of A and B", or "at least one of A or B" refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.

    [0014] The expression "a first", "a second", "the first", or "the second" used in various embodiments of the present disclosure may modify various elements regardless of the order and/or the importance, and is used only to distinguish one element from another element, but does not limit the corresponding elements. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

    [0015] It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) "connected," or "coupled," to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposed between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being "directly connected," or "directly coupled" to another element (second element), there is no element (e.g., third element) interposed between them.

    [0016] The expression "configured to" used in the present disclosure may be exchanged with, for example, "suitable for", "having the capacity to", "designed to", "adapted to", "made to", or "capable of' according to the situation. The term "configured to" may not necessarily imply "specifically designed to" in hardware. Alternatively, in some situations, the expression "device configured to" may mean that the device, together with other devices or components, "is able to". For example, the phrase "processor adapted (or configured) to perform A, B, and C" may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., Central Processing Unit (CPU) or Application Processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

    [0017] The terms used herein are merely for the purpose of describing particular embodiments and are not intended to limit the scope of other embodiments. A singular expression may include a plural expression unless they are definitely different in context. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of the art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

    [0022] Hereinafter, an electronic device according to various embodiments of the present disclosure will be described with reference to the accompanying drawings. In the present disclosure, the term "user" may indicate a person using an electronic device or a device (e.g. an artificial intelligence electronic device) using an electronic device.

    [0023] Referring to FIG. 1, a description will be made of an electronic device 101 in a network environment 100 according to various embodiments of the present disclosure. The electronic device 101 may include a bus 110, a processor 120, a memory 130, an input/output interface 150, a display 160, and a communication interface 170. In some embodiments of the present disclosure, at least one of the above elements of the electronic device 101 may be omitted from the electronic device 101, or the electronic device 101 may additionally include other elements.

    [0024] The bus 110 may include, for example, a circuit that interconnects the elements 110 to 170 and delivers a communication (e.g., a control message and/or data) between the elements 110 to 170.

    [0025] The processor 120 may include one or more of a Central Processing Unit (CPU), an Application Processor (AP), and a Communication Processor (CP). The processor 120 may perform, for example, calculations or data processing related to control over and/or communication by at least one of the other elements of the electronic device 101.

    [0026] The memory 130 may include a volatile memory and/or a non-volatile memory. The memory 130 may store, for example, commands or data related to at least one of the other elements of the electronic device 101. According to an embodiment of the present disclosure, the memory 130 may store software and/or a program 140. The program 140 may include, for example, a kernel 141, middleware 143, an Application Programming Interface (API) 145, and/or an application program (or an application) 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an "Operating System (OS)."

    [0027] For example, the kernel 141 may control or manage system resources (e.g., the bus 110, the processor 120, the memory 130, and the like) used to execute operations or functions implemented by the other programs (e.g., the middleware 143, the API 145, and the application program 147). Also, the kernel 141 may provide an interface capable of controlling or managing the system resources by accessing the individual elements of the electronic device 101 by using the middleware 143, the API 145, or the application program 147.

    [0028] For example, the middleware 143 may serve as an intermediary that enables the API 145 or the application program 147 to communicate with the kernel 141 and to exchange data therewith.

    [0029] Also, the middleware 143 may process one or more task requests received from the application program 147 according to a priority. For example, the middleware 143 may assign a priority, which enables the use of system resources (e.g., the bus 110, the processor 120, the memory 130, etc.) of the electronic device 101, to at least one of the application programs 147. For example, the middleware 143 may perform scheduling, load balancing, or the like of the one or more task requests by processing the one or more task requests according to the priority assigned to the at least one of the application programs 147.

    [0030] The API 145 is, for example, an interface through which the application 147 controls a function provided by the kernel 141 or the middleware 143, and may include, for example, at least one interface or function (e.g., command) for file control, window control, image processing, character control, or the like.

    [0031] For example, the input/output interface 150 may serve as an interface capable of delivering a command or data, which is input from a user or another external device, to the element(s) other than the input/output interface 150 within the electronic device 101. Also, the input/output interface 150 may output, to the user or another external device, commands or data received from the element(s) other than the input/output interface 150 within the electronic device 101.

    [0032] Examples of the display 160 may include a Liquid Crystal Display (LCD), a Light-Emitting Diode (LED) display, an Organic Light-Emitting Diode (OLED) display, a MicroElectroMechanical Systems (MEMS) display, and an electronic paper display. For example, the display 160 may display various pieces of content (e.g., text, images, videos, icons, symbols, etc.) to the user. The display 160 may include a touch screen, and may receive, for example, a touch input, a gesture input, a proximity input, or a hovering input provided by an electronic pen or a body part of the user.

    [0033] The communication interface 170 may establish, for example, communication between the electronic device 101 and an external device (e.g., a first external electronic device 102, a second external electronic device 104, or a server 106). For example, the communication interface 170 may be connected to a network 162 through wireless or wired communication and may communicate with the external device (e.g., the second external electronic device 104 or the server 106).

    [0034] The wireless communication may be performed by using at least one of, for example, Long-Term Evolution (LTE), LTE-Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), WiBro (Wireless Broadband), and Global System for Mobile Communications (GSM), as a cellular communication protocol. Also, examples of the wireless communication may include short-range communication 164. The short-range communication 164 may be performed by using at least one of, for example, Wi-Fi, Bluetooth, Near Field Communication (NFC), and Global Navigation Satellite System (GNSS). The GNSS may include at least one of, for example, a Global Positioning System (GPS), a Global Navigation Satellite System (Glonass), a Beidou Navigation Satellite System (hereinafter "Beidou"), and a European Global Satellite-based Navigation System (Galileo), according to a use area, a bandwidth, or the like. Hereinafter, in the present disclosure, the term "GPS" may be used interchangeably with the term "GNSS." The wired communication may be performed by using at least one of, for example, a Universal Serial Bus (USB), a High Definition Multimedia Interface (HDMI), Recommended Standard 232 (RS-232), and a Plain Old Telephone Service (POTS). The network 162 may include at least one of communication networks, such as a computer network (e.g., a Local Area Network (LAN), or a Wide Area Network (WAN)), the Internet, and a telephone network.

    [0035] Each of the first and second external electronic devices 102 and 104 may be of a type identical to or different from that of the electronic device 101. According to an embodiment of the present disclosure, the server 106 may include a group of one or more servers. According to various embodiments of the present disclosure, all or some of operations performed by the electronic device 101 may be performed by another electronic device or multiple electronic devices (e.g., the first and second external electronic devices 102 and 104 or the server 106). According to an embodiment of the present disclosure, if the electronic device 101 needs to perform some functions or services automatically or by a request, the electronic device 101 may send, to another device (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106), a request for performing at least some functions related to the functions or services, instead of performing the functions or services by itself, or additionally. Another electronic device (e.g., the first external electronic device 102, the second external electronic device 104, or the server 106) may execute the requested functions or the additional functions, and may deliver a result of the execution to the electronic device 101. The electronic device 101 may process the received result without any change or additionally and may provide the requested functions or services. To this end, use may be made of, for example, cloud computing technology, distributed computing technology, or client-server computing technology.

    [0036] The GPS module 190 may receive a GPS signal from a satellite, and may output a Global Positioning System Fixed Data (GPGGA) signal, a GNSS Satellites in View (GPGSV) signal, and a GNSS Dilution of Precision (DOP) and Active Satellites (GPGSA) signal to the processor 120.

    [0037] According to various embodiments of the present disclosure, the processor 120 may be electrically connected to the memory 130. The memory 130 may store instructions that, if executed by the processor 120, cause the processor 120 to determine whether an obstacle exists in a first direction with the electronic device as a reference, to determine that the electronic device is disposed indoors if it is determined that the obstacle exists in the first direction, and to determine that the electronic device is disposed outdoors if it is determined that the obstacle does not exist in the first direction.

    [0038] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine whether the obstacle exists in the first direction by using the GPS signal.

    [0039] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine a location of a satellite in a celestial sphere map by analyzing a GPS signal, and to determine that the obstacle exists in the first direction if the satellite does not exist in a preset range of the celestial sphere map, or to determine that the obstacle does not exist in the first direction if the satellite exists in the preset range of the celestial sphere map.

    [0040] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine a location of a satellite in a celestial sphere map by analyzing a GPS signal, and to determine that the obstacle does not exist in the first direction if a strength of a GPS signal corresponding to the satellite located in a preset range of the celestial sphere map exceeds a preset threshold, or to determine that the obstacle exists in the first direction if the strength of the GPS signal corresponding to the satellite located in the preset range of the celestial sphere map is less than or equal to the preset threshold.

    [0041] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine the location of the satellite in the celestial sphere map by analyzing a GPGSV signal of the GPS signal.

    [0042] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine the preset range by analyzing a GPGSA signal of the GPS signal.

    [0043] According to various embodiments of the present disclosure, the communication module 170 may receive satellite location information from the server. According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine a location of a satellite in a celestial sphere map by analyzing a GPS signal, to compare the determined location of the satellite with the received satellite location information, and to determine whether the obstacle exists in the first direction according to a result of the comparison.

    [0044] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine whether there exists a satellite from which a signal has not been received among pieces of the received satellite location information, and to determine that an obstacle exists in a direction corresponding to the location of the satellite from which the signal has not been received.

    [0045] According to various embodiments of the present disclosure, the memory 130 may further store instructions that, if executed by the processor 120, cause the processor 120 to determine that the electronic device is disposed indoors or outdoors according to whether a direction in which the obstacle exists is the first direction.

    [0091] As described above, the electronic device 101 may determine whether the electronic device 101 exists indoors or outdoors according to whether the obstalce exists in the first direction 501.

    [0092] In various embodiments of the present disclosure, the electronic device 101 may provide various services according to whether the electronic device 101 exists indoors or outdoors.

    [0095] In operation 620, the electronic device 101 may determine whether an obstacle exists in a first direction, by using the received GPS signal. For example, referring to FIG. 7A, the electronic device 101 may receive GPS signals 711 to 714 from one or more satellites 701 to 704, respectively. As illustrated in FIG. 7A, if the obstacle is not disposed between the electronic device 101 and the satellites 701 to 704, the electronic device 101 may receive the GPS signals 711 to 714. If the GPS signals 711 to 714 are received from the first direction, the electronic device 101 may determine that the obstacle does not exist in the first direction. Meanwhile, referring to FIG. 7B, the electronic device 101 may not receive the GPS signals 711 to 714 from the one or more satellites 701 to 704, respectively. As illustrated in FIG. 7B, if the obstacle 720 is disposed between the electronic device 101 and the satellites 701 to 704, the electronic device 101 may not receive the GPS signals 711 to 714. If the GPS signals 711 to 714 are not received from the first direction, the electronic device 101 may determine that the obstacle 720 exists in the first direction. Alternatively, if strengths of the GPS signals 711 to 714 received from the first direction are less than a preset threshold, the electronic device 101 may determine that the obstacle 720 exists in the first direction.

    [0096] In operation 630, the electronic device 101 may determine whether the electronic device 101 is disposed indoors or outdoors, according to a result of determining whether the obstacle exists in the first direction. If it is determined that the obstacle exists in the first direction, the electronic device 101 may determine that the electronic device 101 is disposed indoors.

    [0098] In operation 810, the electronic device 101 may receive a GPS signal from a satellite. In various embodiments of the present disclosure, the GPS module of the electronic device 101 may analyze a GPS signal received according to the NMEA 0183 standard. The GPS module may analyze the GPS signal and may deliver a GPGGA signal, a GPGSV signal, and a GPGSA signal to a host, namely, the processor. The electronic device 101 may acquire GPS-related information by using the acquired GPGGA signal, GPGSV signal, and GPGSA signal. The GPGGA signal may include latitude coordinates and longitude coordinates which are based on the fixed WGS-84 of the GPS module. The GPGSV signal is information on a satellite that transmits a GPS signal, and may include a Signal-to-Noise Ratio (SNR) of a GPS signal for each satellite, an azimuth for each satellite, and an elevation for each satellite. The GPGSA signal may include a Dilution of Precision (DOP) of a satellite. The DOP of a satellite may signify the scattering degree of satellites, and may represent the degree that satellites scatter.

    [0099] In operation 820, the electronic device 101 may determine a location of the satellite in the celestial sphere map by analyzing a GPGSV signal. For example, the electronic device 101 may configure the celestial sphere map illustrated in FIG. 9A, and may determine satellite locations 911 to 916 in the celestial sphere map. In FIG. 9A, the upward direction of the celestial sphere map indicates the north with a user as a reference, the downward direction thereof indicates the south with the user as the reference, the right thereof indicates the east with the user as the reference, and the left thereof indicates the west with the user as the reference. Also, the origin of the celestial sphere map may indicate an upward direction, namely, a ceiling of the celestial sphere, with the user as the reference. As described above, the first direction may be the upward direction perpendicular to the surface of the earth, and thus, a direction of the ceiling of the celestial sphere may be set to the first direction.

    [0100] In operation 830, the electronic device 101 may determine whether a satellite exists in a preset range of the celestial sphere map. For example, the electronic device 101 may set a preset area 910 as illustrated in FIG. 9A. Here, the preset area 910 is an area corresponding to the first direction, and may correspond to the surface area of a ceiling in a case if existing indoors. For example, as illustrated in FIG. 9B, the preset area 910 corresponding to a base side 930 of a cone having a first angle θ may be set in the first direction of the electronic device 101. Here, the surface area of the base side 930 may be set on the basis of the elevation of the electronic device 101 in a typical situation, the surface area of the ceiling, and the distance from the electronic device 101 to the ceiling, and the like. In another embodiment of the present disclosure, the electronic device 101 may set the preset area 910 so as to correspond to an area where at least one satellite may be observed in a typical situation. More specifically, the electronic device 101 may analyze a database on a satellite location, and thereby may determine the size of the area where at least one satellite may be observed. Meanwhile, as described in more detail below, the electronic device 101 may adjust the preset area 910 by using a GPS signal.

    [0101] In the embodiment of FIG. 9A, the electronic device 101 may determine that a fourth satellite 914 and a fifth satellite 915 are included in the preset area 910.

    [0102] If it is determined that a satellite is not disposed in the preset area 910, in operation 840, the electronic device 101 may determine that the electronic device 101 is disposed indoors. If it is determined that the satellite is disposed in the preset area 910, in operation 850, the electronic device 101 may determine that the electronic device 101 is disposed outdoors. As described above, the preset area 910 is an area corresponding to the first direction, and the electronic device 101 may determine whether the obstacle exists in the first direction of the electronic device 101, according to whether a satellite is included in the preset area 910. If it is determined that the satellite is not disposed in the preset area 910, the electronic device 101 may determine that the obstacle exists in the first direction and may determine that the electronic device 101 is disposed indoors. If it is determined that the satellite is disposed in the preset area 910, the electronic device 101 may determine that the obstacle does not exist in the first direction and may determine that the electronic device 101 is disposed outdoors.

    [0103] FIG. 9C is a conceptual view illustrating the location of a satellite in the celestial sphere map according to various embodiments of the present disclosure. The electronic device 101 may confirm locations of satellites 941 to 944 in the celestial sphere map as illustrated in FIG. 9C by analyzing a GPGSV signal. The electronic device 101 may confirm that a satellite is not disposed in the first area 910. The electronic device 101 may determine that the obstacle exists in the first direction, and may thus determine that the electronic device 101 is disposed indoors.

    [0104] FIG. 8B is a flowchart illustrating a control method of an electronic device according to various embodiments of the present disclosure.

    [0105] In operation 810, the electronic device 101 may receive a GPS signal from a satellite. In operation 820, the electronic device 101 may determine a location of the satellite in the celestial sphere map by analyzing a GPGSV signal.

    [0106] In operation 835, the electronic device 101 may determine whether the strength of a GPS signal from a satellite in a preset range of the celestial sphere map exceeds a preset threshold. For example, the electronic device 101 may acquire the strengths of GPS signals from the fourth satellite 914 and the fifth satellite 915, which are included in the preset range 910 illustrated in FIG. 9A, by analyzing GPGSV signals.

    [0107] If it is determined that the signal from the satellite in the preset area 910 is less than or equal to the threshold, in operation 840, the electronic device 101 may determine that the electronic device 101 is disposed indoors. If it is determined that the signal from the satellite in the preset area 910 exceeds the threshold, in operation 850, the electronic device 101 may determine that the electronic device 101 is disposed outdoors. As described above, the preset area 910 is an area corresponding to the first direction, and the electronic device 101 may determine whether the obstacle exists in the first direction of the electronic device 101, according to whether the signal from the satellite in the preset area 910 exceeds the threshold. If the obstacle exists in the first direction, the strength of a GPS signal may be relatively weak. Accordingly, if it is determined that the signal from the satellite in the preset area 910 is less than or equal to the threshold, the electronic device 101 may determine that the obstacle exists in the first direction, and may determine that the electronic device 101 is disposed indoors. If it is determined that the signal from the satellite in the preset area 910 exceeds the threshold, the electronic device 101 may determine that the obstacle does not exist in the first direction, and may determine that the electronic device 101 is disposed outdoors.

    [0108] FIG. 10 is a flowchart illustrating a control method of an electronic device according to various embodiments of the present disclosure. The embodiment of FIG. 10 will be described in more detail with reference to FIGs. 11A and 11B. FIGs. 11A and 11B are conceptual views each illustrating a celestial sphere map according to various embodiments of the present disclosure.

    [0109] In operation 1010, the electronic device 101 may receive a GPS signal from a satellite. In operation 1020, the electronic device 101 may determine a location of the satellite in the calestial sphere map by analyzing a GPGSV signal.

    [0110] In operation 1030, the electronic device 101 may determine a preset range by analyzing a GPGSA signal. As described above, the GPGSA signal may include the DOP of a satellite. The DOP of a satellite may signify the scattering degree of satellites, and may represent the degree that satellites scatter. If the DOP is relatively large, it may be determined that the scattering degree of satellites is high. If the DOP is relatively small, it may be determined that the scattering degree of satellites is low. The higher the scattering degree of satellites becomes, the higher the probability that a satallite will exist in a particular range in the celestial sphere map becomes. Also, the lower the scattering degree of satellites becomes, the lower the probability that the satallite will exist in the particular range in the celestial sphere map becomes. Accordingly, the electronic device 101 may determine the preset range in response to the DOP. For example, if the DOP is relatively small, the electronic device 101 may set a preset range 1120 to be relatively large as illustrated in FIG. 11A. As illustrated in FIG. 11A, it can be noted that the scattering degree of satellites 1111 to 1115 in the celestial sphere map is low. Accordingly, the electronic device 101 may acquire a relatively small DOP by analyzing a GPGSA signal. The electronic device 101 may determine the preset range 1120 of a relatively large size in response to the relatively small DOP. Alternatively, in FIG. 11B, it can be noted that the scattering degree of satellites 1131 to 1135 in the celestial sphere map is relatively high. Accordingly, the electronic device 101 may acquire a relatively large DOP by analyzing a GPGSA signal. The electronic device 101 may determine a preset range 1140 of a relatively small size in response to the relatively large DOP.

    [0111] In operation 1040, the electronic device 101 may determine whether a satellite exists in the preset range of the celestial sphere map. In operation 1050, if it is determined that the satellite does not exist in the preset range of the celestial sphere map, the electronic device 101 may determine that the electronic device 101 is disposed indoors. In operation 1060, if it is determined that the satellite exists in the preset range of the celestial sphere map, the electronic device 101 may determine that the electronic device 101 is disposed outdoors. Meanwhile, in various embodiments of the present disclosure, the electronic device 101 may determine whether the electronic device 101 is disposed indoors or outdoors, according to whether the strength of a signal from the satellite in the preset range exceeds a threshold.

    [0112] That is, as described above, the electronic device 101 may adjust the preset range for determining whether the electronic device 101 is disposed indoors or outdoors.

    [0113] FIG. 12 is a flow diagram illustrating a control method of an electronic device according to various embodiments of the present disclosure. The embodiment of FIG. 12 will be described in more detail with reference to FIG. 13. FIG. 13 is conceptual views each illustrating a celestial sphere map and satellite location information according to various embodiments of the present disclosure.

    [0114] In operation 1210, the electronic device 101 may receive satellite location information from a server 1201. For example, North American Aerospace Defense Command (NORAD) and National Aeronautics and Space Administration (NASA) disclose location information of all the satellites orbiting the earth. The server 1201 may transmit, for example, satellite location information 1320 of FIG. 13 to the electronic device 101. The satellite location information 1320 may be transmitted to the electronic device 101 by the server 1201, or may be generated by the electronic device 101 on the basis of information received from the server 1201. Specifically, the satellite location information 1320 may be generated by the server 1201, or may be generated by the electronic device 101. In the embodiment of FIG. 13, the satellite location information 1320 may be information designating the respective locations of multiple satellites 1321 to 1337 in the celestial sphere map.

    [0115] In operation 1220, the electronic device 101 may receive a GPS signal from a satellite 1200. Although the electronic device 101 is illustrated as receiving a GPS signal from the one satellite 1200 in FIG. 12, this configuration is illustrated for illustrative purposes only, and the electronic device 101 may receive GPS signals from respective multiple satellites. The electronic device 101 may receive respective GPS signals from at least four satellites along the LOS of the electronic device 101.

    [0116] In operation 1230, the electronic device 101 may determine a location of the satellite in the celestial sphere map by analyzing a GPGSV signal of the GPS signal received from the satellite 1200. As described above, the electronic device 101 may receive GPS signals from the respective multiple satellites existing along the LOS, and may thus determine, for example, satellite locations 1310 in the celestial sphere map illustrated in FIG. 13. The electronic device 101 may determine respective locations of multiple satellites 1311 to 1314 in the celestial sphere map.

    [0117] In operation 1240, the electronic device 101 may compare the determined locations of the satellites with the received satellite location information. The electronic device 101 may compare, for example, the determined satellite locations 1311 to 1314 of FIG. 13 with pieces of the received satellite location information 1321 to 1327. The electronic device 101 may confirm that some pieces of satellite location information 1335 and 1336 from among pieces of the received satellite location information 1321 to 1327 do not match the determined satellite locations.

    [0118] In operation 1250, the electronic device 101 may determine whether the electronic device is disposed indoors or outdoors, according to a result of the comparison. In an embodiment of the present disclosure, if it is determined that a satellite is not disposed in a preset area 1315, the electronic device 101 may determine that the electronic device 101 is disposed indoors. If it is determined that the satellite is disposed in the preset area 1315, the electronic device 101 may determine that the electronic device 101 is disposed outdoors. As described above, the preset area 1315 is an area corresponding to the first direction, and the electronic device 101 may determine whether an obstacle exists in the first direction of the electronic device 101, according to whether the satellite is included in the preset area 1315. If it is determined that the satellite is not disposed in the preset area 1315, the electronic device 101 may determine that the obstacle exists in the first direction, and may determine that the electronic device 101 is disposed indoors. If it is determined that the satellite is disposed in the preset area 1315, the electronic device 101 may determine that the obstacle does not exist in the first direction, and may determine that the electronic device 101 is disposed outdoors.

    [0119] FIG. 14A is a flowchart illustrating a control method of an electronic device according to various embodiments of the present disclosure.

    [0121] In operation 1420, the electronic device 101 may receive a GPS signal from a satellite. In operation 1430, the electronic device 101 may determine a location of the satellite in the celestial sphere map by analyzing a GPGSV signal.

    [0122] In operation 1440, the electronic device 101 may determine whether there exists a satellite from which a signal has not been received among pieces of the received satellite location information. In operation 1450, the electronic device 101 may determine that an obstacle exists in a direction corresponding to the location of the satellite from which the signal has not been received.

    [0123] For example, as illustrated in FIG. 15A, the electronic device 101 may determine that signals from some satellites 1511 and 1512 have not been received among pieces of the received satellite location information 1510. The electronic device 101 may determine a direction, which corresponds to the location of the satellite from which the signal has not been received, in the celestial sphere map. For example, in the embodiment of FIG. 15A, the electronic device 101 may determine that an obstacle exists in a northeast direction with the user as a reference.

    [0124] FIG. 14B is a flowchart illustrating a control method of an electronic device according to various embodiments of the present disclosure.

    [0125] In operation 1450, the electronic device 101 may determine that an obstacle exists in a direction corresponding to the location of a satellite from which a signal has not been received. In operation 1460, the electronic device 101 may determine whether the electronic device 101 is disposed indoors or outdoors, according to the direction in which the obstacle exists. For example, if a direction in which the electronic device 101 has determined that the obstacle exists belongs to the first direction (i.e., the upward direction of the user), the electronic device 101 may determine that the electronic device 101 is disposed indoors.

    [0126] FIG. 14C is a flowchart illustrating a control method of an electronic device according to various embodiments of the present disclosure.

    [0127] In operation 1450, the electronic device 101 may determine that an obstacle exists in a direction corresponding to the location of a satellite from which a signal has not been received. In operation 1470, the electronic device 101 may determine an indoor geography in which the electronic device 101 is disposed, according to a direction in which the obstacle exists.

    [0128] For example, as illustrated in FIG. 15A, the electronic device 101 may determine that signals from the some satellites 1511 and 1512 have not been received among pieces of the received satellite location information 1510. The electronic device 101 may determine a direction, which corresponds to the location of the satellite from which the signal has not been received, in the celestial sphere map. For example, in the embodiment of FIG. 15A, the electronic device 101 may determine that an obstacle exists in a northeast direction with the user as a reference. Accordingly, as illustrated in FIG. 15B, the electronic device 101 may determine that a wall exists in a northeast direction with the electronic device 101 as a reference, and may determine that a window 1540 having no wall is disposed in a west direction.

    [0129] FIG. 16 is a flowchart illustrating a control method of an electronic device according to various embodiments of the present disclosure. The embodiment of FIG. 16 will be described in more detail with reference to FIG. 17.

    [0130] In operation 1610, the electronic device 101 may transmit a transmission signal. For example, as illustrated in FIG. 17, the electronic device 101 may transmit a transmission signal 1721. For example, the electronic device 101 may include a TOF camera. If the electronic device 101 includes the TOF camera, the transmission signal may be light. The electronic device 101 may determine a distance between the electronic device 101 and an object on the basis of information from the TOF camera. In another embodiment of the present disclosure, the electronic device 101 may transmit an RF signal, an ultrasound signal, an infrared signal, or the like.

    [0131] In operation 1620, the electronic device 101 may turn on a module that receives a reflection signal formed by the reflection of the transmission signal. For example, as illustrated in FIG. 17, the electronic device 101 may receive a reflection signal 1722 formed by the transmission signal 1721 reflected by an obstacle 1710. For example, if the electronic device 101 includes the TOF camera, the electronic device 101 may turn on a receptor of the TOF camera and may receive a reflection signal. Alternatively, the electronic device 101 may turn on an RF signal reception module, may set a transducer to a ultrasound reception mode, or may turn on an infrared signal reception module.

    [0132] In operation 1630, the electronic device 101 may determine whether the reflection signal is received. If it is determined that the reflection signal is received, in operation 1640, the electronic device 101 may determine that the electronic device 101 is disposed indoors. If it is determined that the reflection signal is not received, in operation 1650, the electronic device 101 may determine that the electronic device 101 is disposed outdoors. If the reflection signal is received, the electronic device 101 may determine that the obstacle exists, and may determine that the electronic device 101 is disposed indoors. If the reflection signal is not received, the electronic device 101 may determine that the obstacle does not exist, and may determine that the electronic device 101 is disposed outdoors.

    [0133] The electronic device 101 may additionally display a screen that indicates the transmission direction of a transmission signal.

In operation 1840, the electronic device 101 may determine whether the distance between the electronic device 101 and the obstacle is included in a preset range. Here, the preset range may be a distance from a floor to a ceiling in a typical indoor place.

    [0137] If it is determined that the distance between the electronic device 101 and the obstacle is included in the preset range, in operation 1850, the electronic device 101 may determine that the electronic device 101 is disposed indoors. If it is determined that the distance between the electronic device 101 and the obstacle is not included in the preset range, in operation 1860, the electronic device 101 may determine that the electronic device 101 is disposed outdoors.
