SYSTEM AND METHODS FOR CLOSED LOOP DOPPLER TRACKING IN INTER-SATELLITE LINKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240137115 titled 'SYSTEM AND METHODS FOR CLOSED LOOP DOPPLER TRACKING IN INTER-SATELLITE LINKS

Simplified Explanation

The apparatus described in the patent application is designed to receive an input signal from a target apparatus, determine the position information of a source object and a target object, calculate a relative velocity, and adjust a local oscillator frequency based on the Doppler shift measured using the position information.

• Transceiver circuitry receives input signal from target apparatus
• Processing circuitry determines position information of source and target objects
• Relative velocity is calculated based on position information
• Doppler shift or carrier frequency offset in input signal is determined based on relative velocity
• Local oscillator frequency is adjusted based on Doppler shift in initial link acquisition phase
• Doppler is tracked continuously over a range of tens of gigahertz, accounting for phase ambiguities
• Tracked Doppler shift is corrected by adjusting local oscillator frequency and digitally correcting residual Doppler shift

Original Abstract Submitted

an apparatus can include transceiver circuitry to receive an input signal from a target apparatus. the apparatus can further include a processing circuitry to determine position information of a source object and a target object. based on the position information, the processing circuitry can calculate a relative velocity and determine a doppler shift or carrier frequency offset in the input signal based on the relative velocity. the processing circuitry can adjust a local oscillator frequency based on a doppler measured using the position information in an initial link acquisition phase. the processing circuitry can track the doppler continuously over a range of tens of gigahertz accounting for doppler phase ambiguities, and correct for a tracked doppler shift by partially adjusting a local oscillator frequency and by correcting a residual doppler shift digitally.
