    • PURPOSE: A method for compensating Doppler transition frequency in a non-geostationary satellite orbit mobile communication system is provided to reduce the complexity of a frequency synchronous circuit device required from a receiving mobile terminal and easily receive signals by performing accurate and prompt frequency synchronizing with electric calculation. CONSTITUTION: Initial input Doppler transition value is set up by using a pilot signal received from a satellite to adaptively compensate Doppler transition frequency generated by operation of a non-geostationary satellite(S510). Instantaneous satellite location parameter is input(S520). The distance between the satellite and a mobile communication terminal is estimated(S530). The location of the receiving mobile terminal is estimated by using the estimated Doppler transition frequency and the location of the satellite(S540). Instantaneous Doppler transition frequency is predicted by using the estimated location of the receiving mobile terminal(S550). A prediction error is compensated by applying appropriate weight to the predicted instantaneous Doppler transition frequency(S560).
