Abstract: The Agile Earth observation satellite scheduling problem has been one of the most difficult problem in the field of operations research. For Agile satellite, a different observation time means a different observing angle, as a consequence, the attitude transition time between adjacent tasks is also different. Therefore, the Agile Earth observation satellite scheduling problem has a feature of being time-dependent which make the solving more difficult. This article formulated a new model of Agile Earth observation satellite scheduling problem and designed a new solving frame. Enhanced pigeon-inspired optimisation was proposed to solving it, in which guide operator and accelerate operator are introduced to enhance the search capability of the algorithm. After testing on 15 experimental scenarios, the proposed algorithm owns a better performance than the state-of-the-art algorithm.
