1. A method of geolocation of an equipment, comprising:
- receiving, by receiving means situated on said equipment, of positioning information coming from a satellite navigation system, said positioning information containing at least one code phase measurement;
transmitting messages, by transmission means situated on the equipment and belonging to a data collection system, said messages containing said code phase measurements, and measurements on the transmission of the messages, effected by measuring means belonging to said data collection system; and
combining, by processing means remote from the equipment and belonging to said data collection system, said code phase measurements and said measurements on the transmission of the messages, in such a manner as to geolocate said equipment.

Abstract
Method of geolocation employing hybridization of a satellite navigation system and a data collection system. The method minimizes processing time by the means equipping the objects to be geolocated, given the processing effected in “masked time” by remote equipment, typically ground stations of the data collection system. To this end, the method necessitates only acquisition of the code phase of the positioning information coming from the satellite navigation system.
