Patent ID: 7522588

Claim:
An apparatus for processing reference data for wireless assisted positioning using data received from a plurality of reference data sources for subsequent processing by a position determining processor (PDP), comprising: a communication controller to control communication with the reference data sources and to receive the reference data therefrom; a first reference data processor communicatively coupled to the communication controller to receive the reference data therefrom; and a second reference data processor to process the reference data from the plurality of reference data sources, wherein the plurality of reference data sources are associated with a first network and the PDP is associated with a second network, with the first reference data processor being associated with the first network and the second reference data processor being associated with the second network, the first reference data processor functioning in a pass through mode to forward the reference data to the second reference data processor, and wherein the second reference data processor processes the reference data from the reference data sources by comparing raw data from at least two of the plurality of reference data sources to remove redundant reference data and thereby generate processed data, the second reference data processor communicating the processed data to the PDP.
