ABSTRACT:
A method for calculating instantaneous characteristics of a satellite in orbit equipped with a GNSS receiver, capable of performing measurements of pseudo-distance, when fewer than four transmitters are simultaneously in visibility. This method pre-processes quantities measured by the receiver to deliver measurements of pseudo-distance, pseudo-speed and instantaneous pseudo-accelerations, mathematically processes the measured quantities, enhanced by knowledge of complementary data concerning the orbit of the satellite and the receiver, delivering plural solutions, and physically filters the solutions to deliver position and speed of the satellite and clock bias and drift of the receiver.
