In a satellite communication system (10, 30) with at least one ground based transmitter (12, 32), at least one ground based receiver (16, 36) and at least one communication satellite (14, 34), an earth-based receiver (16, 36) self-determines its Doppler correction factors using software algorithms which minimize the amount of hardware required and minimize the time required to acquire the signal.
