Abstract:

Both the Navstar GPS and the GLONASS satellite navigation systems developed respectively by the United States and the Soviet Union are now planned to become operational by 1995. Both systems are capable of providing the civil community with high-precision position-fixes and/or timing references on a continuous, world-wide basis. Already there are several GPS and GLONASS satellites in orbit in order for pre-operational testing to be conducted. Developments in planned use of orbits are discussed as well as the use of the data message to present information on almanacs, ephemerides and satellite clock behaviour
