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 17972965 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 track and correct for Doppler shifts in an input signal received from a target apparatus. Here is a simplified explanation of the abstract:

• Transceiver circuitry receives an input signal from a target apparatus.
• Processing circuitry determines position information of a source object and a target object.
• Relative velocity is calculated based on the position information.
• Doppler shift or carrier frequency offset in the input signal is determined based on the relative velocity.
• Local oscillator frequency is adjusted based on the measured Doppler in an initial link acquisition phase.
• Doppler is continuously tracked over a range of tens of gigahertz, accounting for Doppler 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.
