Abstract
A system for measuring the pseudo range from a first GPS sensor to a designated navigational satellite, for use in a satellite positioning system (SPS) is comprised of first and second GPS sensors for receiving and recording first and second portions of the signal transmitted by the designated navigational satellite, the recordings referred to as the first and second datagrams. The first and second datagrams are transmitted to a datagram processing facility wherein the pseudo range from the first GPS sensor to the designated navigational satellite is extracted. The datagram processing facility for extracting the pseudo range is further comprised of a pseudo range engine for extracting a pseudo range from a datagram received by the first GPS sensor. The location of which is to be determined, the extraction accomplished with the aid of a perfect reference; and a perfect reference engine for generating a perfect reference from a datagram originating with a second GPS sensor designated for the express purpose of perfect reference generation.
