Starlink Analysis – Supplement(6):The Effect of Relativity on OFDM Clock Errors in LEO Communications

I continued reading the Starlink patent US12003350 and came across the following statement: A small change in clock rate is also caused by special (motion) and general (gravity) relativistic effects but it is quite small in low Earth orbits (about 0.2 ppb or parts per billion). This is the relativistic effect considered by Starlink when analyzing synchronization error sources in an OFDM system.…
