Abstract: With the development of society, the demand for remote sensing data is increasing, and the shooting tasks that satellites need to complete are also increasing. Limited by the number of satellites and imaging capabilities, there will be a certain trade-off when shooting. Therefore, the definition proposed in this paper affects the characteristics of satellite observation effectiveness evaluation, generates a comprehensive evaluation model of observation effectiveness, and comprehensively forms observation effectiveness evaluation scores, and then makes reasonable and scientific decisions. Firstly, four description factors are generated for observation effectiveness evaluation. In order to make them comparable and normalize them, the genetic algorithm is used to iteratively select the optimal solution, so as to realize the evaluation of observation tasks. In this paper, the shooting tasks of ZY-3 02 satellite in 2022—2023 and ZY-3 03 satellite in 2022 are selected to verify this method. The experimental results show that the model has good adaptability and can scientifically reflect the comprehensive performance of multi-task observation.

Key words: ZY-3 satellite, satellite imaging planning, multi-feature observation evaluation, cloud amount
