Abstract: The orbit maneuver accuracy of the satellite can be greatly improved by determining the maneuver effect.A method of calibrating the effect of control engines and accelerometer scale error by using the precise orbit parameters,telemetry data for attitude and accelerometer was produced.Then,the successful application of this method to the Chinese first lunar prospector mission was presented.Finally,the sensitivity of the calibrating result to the accuracy of orbit and attitude determination was analyzed.The results prove that the calibration of control effect is feasible,and also very important to deep space exploration in future.
