Classification: CPC H | IPC H

Claim 13:
14. A method for use in a satellite communication system, comprising:
receiving, at a first input of a tracking receiver, a first signal at a first frequency via a first path and a calibration signal at a second frequency;
receiving, at a second input of the tracking receiver, the first signal at the first frequency via a second path and the calibration signal at the second frequency;
outputting the calibration signal to a first coupler coupled with the first path and a second coupler coupled with the second path;
determining a first phase value for the second frequency based at least in part on the calibration signal received at the first input and the second input at the second frequency;
determining, from the first phase value, a second phase value associated with the first frequency based at least in part on a first phase offset between the first frequency and the second frequency, the first phase offset determined based at least in part on a first set of receiver calibration factors; and
generating, based at least in part on the second phase value, a phase correction value for signals received at the first frequency.
