In an on-board satellite clock correction system of the type wherein phase errors between the satellite clock and a ground-based clock are determined and a clock correction value sent to the satellite, the clock correction value is determined by curve-fitting the determined phase errors in accordance with a polynomial function, updating the polynomial function coefficients so as to minimize discrepancy between the determined phase errors and those according to the polynomial function, predicting a clock drift in accordance with the polynomial function and calculating an error correction value in accordance with the predicted clock drift.
