Tracking receiver with integrated phase calibration and method

A system for tracking a satellite, comprising:

• a tracking receiver, including:
• a sum input;
• a difference input;
• a digital signal processor (DSP);
• a first analog-to-digital (A/D) converter coupled between the sum input and the DSP, wherein the first A/D converter is configured to convert a signal received at the sum input into a sum digital signal, and to provide the sum digital signal to the DSP;
• a second A/D converter coupled between the difference input and the DSP, wherein the second A/D converter is configured to convert a signal received at the difference input into a difference digital signal, and to provide the difference digital signal to the DSP;
• and
• a calibration output coupled to the sum input and coupled to the difference input;
• wherein the tracking receiver is configured to generate a calibration signal and provide the calibration signal through the calibration output.
