Abstract
A method and apparatus for location determination of a mobile station (304) in a fixed radiocommunication system having at least one base station (302) reduces the computational load on the mobile station. Satellite ephemeris information and clock correction information are received at a base station and periodically used to calculate satellite position data. The satellite position data are conveyed to the mobile station. At other times, the satellite ephemeris data is used to calculate curve fit data at the base station. The curve fit data is transmitted to the mobile station, reducing the amount of data conveyed over the communication link and the computation load on the mobile station.
