Abstract:

Aiming at the on on-board real-time planning problem of multi-objective observation task for agile remote sensing satellite, a heuristic optimized forward-backward chain combination method for on-board implementation is proposed. In this method, the attitude maneuver ability of agile satellite with two degrees of freedom of rolling and pitching is taken as input, and a heuristic method based on high weight group chain and combining attitude maneuver ability with observation revenue is designed. The Monte Carlo simulation under different maneuverability is completed, the chain selection strategy is optimized, and higher observation revenue is obtained. Experiment shows that the proposed method is effective, has high observation revenue and low computational cost, and can be applied to the on-board autonomous mission planning of agile satellites for a large number of point targets.

Key words: agile remote sensing satellite, autonomous mission planning, multi-targets, on-board planning, optimized forward-backward chains combination method
