Classification: CPC H | IPC H

Claim 0:
1. A system for tracking a satellite, comprising:
an antenna configured to receive a first signal at a first frequency;
a tracking feed; and
a tracking receiver, including
a first input coupled with the antenna to receive the first signal via a first path;
a second input coupled with the tracking feed to receive the first signal via a second path;
a calibration output to output a calibration signal at a second frequency, the calibration output coupled with the first path via a first coupler and coupled with the second path via a second coupler; and
a calibration component coupled with the first input, the second input, and the calibration output, wherein the calibration component is configured to:
store a first set of receiver calibration factors;
determine 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;
determine, 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 the first set of receiver calibration factors; and
generate, based at least in part on the second phase value, a phase correction value for signals received at the first frequency.
