<p>A method and apparatus for compensating an oscillator (108) in a location-enabled wireless device (102) is described. In an example, a mobile device (102) includes a wireless receiver (104) for receiving wireless signals (118) and a GPS receiver (112) for receiving GPS signals (120). The mobile device (102) also includes an oscillator (108) having an associated temperature model (110). A frequency error (126) is derived from a wireless signal. The temperature model (110) is adjusted in response to the frequency error (126) and a temperature proximate the oscillator (108). Frequency error of the oscillator (108) is compensated using the adjusted temperature model. In another example, a frequency error is derived using a second oscillator within the wireless receiver (104).</p> |
