[0005]

In the positioning, the time is synchronized among a plurality of satellites, and the user terminal processes the current position from the synchronization signal and the satellite position data obtained by the distance measurement between the satellites. The voice signal for communication is also digitized, and it is converted into a block / compression code to improve the efficiency of the line. In addition, as satellite electronic equipment becomes more sophisticated, processing operations such as satellite orbit determination by ground station and inter-satellite distance measurement, automatic line switching, onboard switch function, and billing will be carried out.
