METHOD FOR LOCATING A TRANSMITTER WITH UNKNOWN POSITION USING SYNCHRONISED RECEIVERS WITH KNOWN POSITIONS

摘要

The invention relates to a method for locating a signal transmitter (5) of which the position is unknown by means of signal receivers (1 2 3) which are synchronised together on a common time reference and of which the positions are known comprising: a step of multilateration (40) by arrival time difference which is carried out with the signals transmitted by the transmitter (5) with unknown position and received by the receivers (1 2 3) respectively characterised in that: said step of multilateration (40) by arrival time difference is preceded by a step of assessing (30) time offsets between the values of the common time reference which are respectively known by the respective receivers (1 2 3) said step of multilateration (40) by arrival time difference is carried out by correcting (41) said time offsets so as to retime the receivers (1 2 3) to a single common time reference value.
