 F real = F nom (1 + V/C)





V = relative speed of the sat on Km/s

C = light speed (300.000 Km/s)

Note that only the component of V that is towards or away from the operator affects the frequency. For example, at TCA, the satellite is still moving at around 7.5km/s relative to the observer, but the motion is neither towards or away from the observer, so at that instant, the Doppler shift is zero.
