Abstract (en)
[origin: WO2018189430A1] The invention relates to a device for relative location, comprising at least three nodes remote from one another. According to the invention, the node (A) comprises a unit (AER), capable of triggering an exchange of messages (M1, M2) to go back and forth with a second unit (BER) present in node (B), the node (A) comprising a unit (AC) for calculating a time-of-flight (Tab) of the message (M1, M2), the unit (AER) being capable of transmitting a message (M5) containing a piece of information (INF1) indicating the time-of-flight (Tab), the node (C) comprising a unit (CER), capable of triggering an exchange of messages (M3, M4) with the unit (AER) and a unit (CC) for calculating a time-of-flight (Tac) of the message (M3, M4), the unit (CER) being capable of receiving messages (M1, M2, M5), the node (C) comprising a time measurement unit (CMT) for measuring times of receipt (T1, T2) of the messages (M1, M2), the unit (CC) being capable of calculating a time-of-flight (Tbc) of the message (M2) from node (B) to node (C) on the basis of times (T1, T2), time-of-flight (Tac) and the piece of information (INF1), contained in the message (M5).
