ABSTRACT:
A positioning system where receiving stations such as multipurpose mobile communications devices can calculate their position. The system includes base stations adapted to receive position information from the receiving stations over a communications path of a mobile telephone system. The system allows the receiving stations to receive a correction signal from a correction station over the communications path on a special signaling layer such that the receiving stations can calculate a corrected position. The system can be used in conjunction with many forms of mobile telephone systems.
