Abstract  Abstract

Methods and apparatuses which use satellite position system (SPS) reference receivers. In one example of the invention a plurality of SPS reference receivers such as Global Positioning System (GPS) reference receivers each having a known position are dispersed over a geographical region. Each of the SPS reference receivers transmits into a communication network a representation of at least a portion of a satellite navigation message such as satellite ephemeris data received from SPS satellites in view of the particular SPS reference receiver. A plurality of digital processing systems such as a first and a second digital processing systems are coupled to the communication network to receive the satellite ephemeris data which is transmitted through the communication network.
