Title (EN) LOCAL CLOCK FREQUENCY CALIBRATION USING LOW EARTH ORBIT (LEO) SATELLITES
(FR) ÉTALONNAGE DE FRÉQUENCE D'HORLOGE LOCALE À L'AIDE DE SATELLITES À ORBITE BASSE (LEO)
Abstract:
(EN) 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.
(FR) L'invention porte sur diverses techniques destinées à étalonner une fréquence d'une horloge locale à l'aide d'un signal de satellite. Dans un exemple, un procédé de transfert de stabilité de fréquence d'un satellite à un dispositif comprend la réception d'un signal provenant du satellite. Le procédé comprend également la détermination d'une phase de code à partir du signal de satellite. Le procédé comprend en outre la réception d'informations d'aide. De plus, le procédé comprend l'étalonnage d'une fréquence d'une horloge locale du dispositif, à l'aide de la phase de code et des informations d'aide, afin de synchroniser sensiblement la fréquence d'horloge locale sur la fréquence d'horloge de satellite.
