Abstract  Abstract

A method and an apparatus for operating a satellite positioning system (SPS) receiver in a client/server architecture. In one example of a method a first plurality of pseudoranges is determined at a first time and a second plurality of pseudoranges is determined at a second time which is after the first time. The first and the second pluralities of pseudoranges are stored. After the second time the first and the second pluralities of pseudoranges are transmitted to a location server normally in one transmission. The location server then determines a first position from the first plurality of pseudoranges and a second position from the second plurality of pseudoranges. In one particular example the first and second pseudoranges are transmitted in response to a predetermined type of event and the location server stores a collection of differential GPS data which has been collected over time.
