Method and apparatus for managing time in a satellite positioning system |
摘要 |
Method and apparatus for time management in a position location system is described. In one example, a time relation is received at a server. The time relation includes a relationship between an air-interface time of a base station and a satellite time for a satellite constellation from a first satellite positioning system (SPS) receiver. The time relation is then stored in the server. In another example, satellite time is determined at a first time for a satellite constellation at an SPS receiver. A time offset is determined between the satellite time and an air-interface time of a base station. The time offset is stored within the SPS receiver. A position of the SPS receiver is computed at a second time using satellite measurements and the stored time offset.
