Abstract :
A hybrid satellite system has been developed which can provide both communications and positioning services in one system using two geostationary satellites. The distinctive feature is that location information can be provided by transmitting and receiving ranging signals over the same channel as communications through two geostationary satellites. The system configurations of two different methods are described
