FIELD: geography.
SUBSTANCE: invention relates to a system of geographical location. Proposed system of geographical location of at least one radio signal transmitter ES located on the Earth's surface, comprises: set of satellites (SAT1, SAT2, SAT3) equipped with receiving antennas (ANT1, ANT2, ANT3) adapted for receiving said signals and a main extended interferometry device; intersatellite relative metrology device for determining the relative positions of said satellites (SAT1, SAT2, SAT3) to one another, including at least one dedicated sensor (CAPTd_1, CAPTd_2 and CAPTd_3) for each satellite (SAT1, SAT2 and SAT3), and intersatellite communication modules (COMM1, COMM2 and COMM3); device for dating (DAT1, DAT2, DAT3) the received signals, based on the determining of the relative positions of the satellites (SAT1, SAT2, SAT3) to one another, issued by said intersatellite relative metrology device; auxiliary interferometry device including at least one set of at least three antennas (ANT21_3, ANT22_3, ANT23_3) of a satellite, ground base station (SBS), and a device for transmitting measurements acquired on the satellites to ground base station (SBS) and means of determining an absolute position (DPA) of at least one of the satellites (SAT1, SAT2, SAT3).
EFFECT: technical result is high location accuracy.
