摘要： A global positioning receiver unit utilizes a temperature compensated oscillator (48) and a unit controller (145). The temperature compensated oscillator (48) generates a clock signal, and the unit controller (145) is configured to track GPS time based on the clock signal while the receiver unit is in a sleep state. The unit controller is further configured to perform a position fix based on a satellite signal and the GPS time tracked by the unit controller.
