LOCAL CLOCK FREQUENCY CALIBRATION USING LOW EARTH ORBIT (LEO) SATELLITES

摘要

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