  • Patent number: 12578412
    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.

  • Patent number: 12199711
    Abstract: An apparatus as described herein may include an antenna array that receives radio frequency signals and outputs analog signals. The apparatus may also include analog to digital signal converters that convert the analog signals into digital sample streams. Also, the apparatus may include a sample buffer that buffers subsets of the digital sample streams and a beamformer that uses the digital sample streams to generate one or more beam signals. Additionally, the apparatus may include a processor that determines a spatial characteristic or a spectral characteristic for the radio frequency signals based on the subsets of the digital sample streams.
