In this paper, the autonomous navigation method based on the earth sensor and the star sensor on passive section during the multi-satellites mission is studied. The orbit prediction is given by the initial state which is determined by least square method. Digital simulations are conducted to analyze the influence of sampling period, measured arc length, accuracy of measurement, reference star positions and installation errors on the position accuracy. It is indicated that the effect of measuring errors is greater than the installation errors.
