ABSTRACT:
A position location system, apparatus, and method are disclosed. A wireless device includes a satellite positioning system (SPS) receiver and position location processor. The SPS receiver detects the availability of positioning signals and the position location processor determines an initial position of the wireless device based upon the positioning signals. A controller generates power saving events when the positioning signals are detected as being available. The controller determines the timing and duration of the power saving events. During a power saving event, the SPS receiver is deactivated and/or processing of the positioning signals is suspended to reduce power consumption of the wireless device. The initial position is updated based upon relative positioning information from one or more sensors during the power saving event. The controller activates the SPS receiver and resumes processing of the positioning signals following the power saving event.
