Satellite Ephemeris Estimator
Passive ephemeris estimation add-on to geolocation system
Principles
The passive method for geostationary satellite ephemeris estimation is based on
differences distances measurement between the satellite and three ground stations
installed in three different locations with an average 300 km distance gap.

Satellite Ephemeris Estimator
Passive ephemeris estimation add-on to geolocation system
Accuracy
The main purpose is to reach the accuracy at which one can use geolocation results without
the use of additional reference transmitters: the operating mode then solely relies on a
single reference carrier.
The system continuously streams main/mirror orbital data to the geolocation system: after
stabilization phase, up to date, accurate data are available upon triggering of a geolocation
task
