System and method for reference data processing in network assisted position determination

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;
• and
• a first processor communicatively coupled to the communication controller to receive the reference data therefrom, the first processor processing the reference data from the reference data sources to remove redundant reference data and thereby generate processed data, the communication controller communicating the processed data to the PDP.

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:

• first processor means for processing the reference data from the reference data sources to remove redundant reference data and thereby generate processed data;
• and
• communication means for communicating the processed data to the PDP.

A computer-readable medium whose contents cause a first computer system to process 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), by causing the first computer system to:

• process the reference data from the reference data sources to remove redundant reference data and thereby generate processed data;
• and
• communicate the processed data to the PDP.
