Abstract
A method and device for managing a reference oscillator within a wireless device is presented. The method includes selecting reference oscillator parameters associated with the lowest reference oscillator error, where the selection is based upon reference oscillator parameters derived using different technologies within a wireless device, acquiring a satellite based upon the selected reference parameters, determining the quality of the satellite-based position fix, and updating the reference oscillator parameters based upon the quality of the satellite-based position fix. The wireless device includes a wireless communications system, a satellite positioning system (SPS) receiver, a reference oscillator connected to the wireless communications system and SPS receiver, and a mobile controller connected to the reference oscillator, SPS, and wireless communications system, and a memory connected to the mobile controller, where the memory stores a reference oscillator parameter table and instructions causing the mobile controller to execute the aforementioned method.
