Using multiple sources of location-aid data to determine position information

摘要

A wireless location/position computation system, device, and method are directed to multiple aid-data sources each providing location-related aid information, a wireless device configured to communicate with the aid-data sources, and a location computation module either integrated with or external to the wireless device. The wireless device may include a transceiver to communicate wireless, data and other signals. The wireless device may receive a position request to compute a position of the wireless device, and in response, initiate a compute-position session. In the compute-position session, the wireless device sends aid requests to and retrieves the location-related aid information from the aid-data sources and processes the location-related aid information from the aid-data sources to generate integrated location information. The location computation module may compute the position of the wireless device based on the integrated location information and satellite location information received from a satellite.

1. A wireless device, comprising:
a transceiver configured to transmit and receive wireless signals; and a location core module comprising a processor configured to: receive a position request to compute a position of the wireless device, and responsive to the position request, initiate a compute-position session in which the processor is further configured to:
send aid requests for location-related aid information,receive the location-related aid information, wherein the location-related aid information comprises satellite orbital information, and/or satellite-related reference and status information,process the location-related aid information to generate integrated location information,track and acquire a satellite based on the integrated location information, andeither compute the position of the wireless device based on the integrated location information and satellite location information received from the satellite, or provide the integrated location information and/or the satellite location information to a location computation module external to the wireless device to compute the position of the wireless device.
