Audit the frequency. Calculate the Doppler frequency shift for satellite communications based on orbital relative velocity.
At a carrier frequency of 1.575 GHz, the high orbital velocity of 7000 m/s causes a shift of 36.78 kHz. Without active frequency tracking, the receiver will fail to lock onto the signal due to this mismatch.
