US Patent:

20210141046, May 13, 2021

Filed:

Jan 22, 2021

Appl. No.:

17/156248

Inventors:

- Carlsbad CA, US
Brian D. Chandler - Atlanta GA, US
David E. Sinyard - Sugar Hill GA, US
Charles M. Luke - Cumming GA, US

International Classification:

G01S 3/02
G01S 3/48

Abstract:

A system and method of the disclosure relates to satellite tracking. The system may comprise a tracking receiver that includes a first analog-to-digital (A/D) converter coupled between a sum input and a digital signal processor (DSP), a second A/D converter coupled between a difference input and the DSP, and a calibration output coupled to the sum input and coupled to the difference input. The first A/D converter may convert an signal received at the sum input into a sum digital signal, and provide the sum digital signal to the DSP. The second A/D converter may convert an signal received at the difference input into a difference digital signal, and provide the difference digital signal to the DSP. The tracking receiver may generate an calibration signal and provide the calibration signal through the calibration output.
