ABSTRACT:
Various techniques are provided for calibrating a frequency of a local clock using a satellite signal. In one example, a method of transferring frequency stability from a satellite to a device includes receiving a signal from the satellite. The method also includes determining a code phase from the satellite signal. The method further includes receiving aiding information. In addition, the method includes calibrating a frequency of a local clock of the device using the code phase and the aiding information to substantially synchronize the local clock frequency with a satellite clock frequency.
