SATELLITE POSITIONING REFERENCE SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide an improved method and an apparatus for securing the flexibility of the positioning of a positioning server.

SOLUTION: A plurality of digital processing systems are coupled to a communication network to receive satellite ephemeris data which are transmitted through the communication network. A digital processing system receives pseudorange data from a SPS mobile receiver and calculates the position information of the SPS mobile receiver from the representation of the pseudorange data and from satellite ephemeris data received from the communication network. The digital processing system may also receive pseudorange correction data from the communication network and use these correction data to correct the pseudorange data to provide the representation of the pseudorange data.
