METHOD AND SYSTEM FOR MONITORING A PHASE FOR TRANSFERRING A SATELLITE FROM AN INITIAL ORBIT TO A MISSION ORBIT

摘要

the present invention relates to a method (70) of a phase controlthe transfer of a satellite (20) in earth orbit.the so-called initial orbit to another orbit, known as the orbitmission, including a transfer meanselectric propulsion. the method includes a step of monitoringto estimate the direction of the satellite during thetransfer phase by means of an array (30) includes an eartha plurality of antennas, each elementary (31)basic antenna main lobe of radiation with a wideequal to or greater than 20, the basic units(31) being oriented so that their respective field of vision.the direction of satellite are estimated ataccording to at least one of the phase difference between signals.corresponding to a signal issued by the target satellite.a pair of antennas and received basic (31).
