Abstract
Generally, system and method for calibration an in-orbit satellite are provided. The method may comprise transmitting, by a Geosynchronous (GEO) satellite, a GEO satellite signal and receiving, by a Low Earth Orbiting (LEO) satellite, the GEO satellite signal when the LEO satellite crosses a predetermined transmission footprint of the GEO satellite at a predetermined LEO satellite location. The method may comprise determining, by a base station, a GEO satellite location at which the GEO satellite signal is received by the LEO satellite. The method may comprise comparing, by the base station, the transmitted GEO satellite signal and the received GEO satellite signal and further determining, by the base station, based on at least one of the comparison thereof, the predetermined LEO satellite location and the GEO satellite location, a GEO satellite transmission performance at a specific geographical location on ground.
