Reverse frequency and time aiding

摘要

The present system relates to a GNSS receiver that includes a processor. The processor is configured to receive a temperature signal from a temperature sensor indicating an operating temperature of an resonator. The processor is also configured to compute a frequency and a frequency correction data of the resonator based on the temperature and a frequency model of the resonator. The processor then transmits the frequency correction data to an RF receiver which utilizes the frequency correction data and the resonator to receive and RF signal.

1. A global navigation satellite system (GNSS) receiver, comprising:
a processor configured to:
receive a temperature signal from a temperature sensor that indicates an operating temperature of a resonator,update a frequency model of the resonator based on a frequency error between a frequency of the resonator and a frequency determined from received satellite signals,compute a frequency and a frequency correction data of the resonator based on the temperature signal and the updated frequency model of the resonator,transmit the frequency correction data to a radio frequency (RF) receiver separate from the GNSS receiver, the RF receiver using the frequency correction data and the resonator to receive an RF signal different from the satellite signals,wherein the GNSS receiver uses the frequency correction data to receive satellite signals.
