Abstract: In the multi-satellite scheduling system of the earth observing system, considering the satellite has the capability of continuous side shift and multiple data compression rate, themulti-satellite scheduling model was constructed. Based on this model, a new scheduling and data transmission method for multi-satellite was designed and implemented,including an imaging scheduling algorithm considering continuous side shift and a data transmission method considering task priority. The experiment results show that themethod can reduce the cost and meet the application requirements.
