Abstract (en)

[origin: WO2020119841A1] In a method and with a device (100) for position determination by means of inertial navigation, a current position (103) is determined from a known starting position (104) and starting orientation by sensing accelerations and rotation rates. To do this, sensors (10) are used to sense accelerations and rotation rates, and the accelerations and rotation rates acting on the sensors (10) along or about three sensor axes are calculated. An evaluation device (13) is used to determine a position from the data of the individual sensors (10), and the vector components of the positions determined are then added in a weighted manner. The weightings are determined by calibration.
