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.
