Abstract

The invention provides an agile remote sensing satellite multi-target in-orbit observation method, which comprises the steps of acquiring longitude and latitude information, observation weight and observation starting point information of multiple targets as input conditions of task planning; during forward observation, combining several continuous targets in forward observation into a forward observation sequence so as to form a plurality of forward chains; during backward observation, combining several continuous targets in backward observation into a backward observation sequence so as to form a plurality of backward chains; according to the earnings after different forward chains and backward chains are combined, determining a combination of the forward chains and the backward chains by combining the attitude maneuver cost generated in the observation direction, adjusting the number of targets on the forward chains or the backward chains according to the combination of the forwardchains and the backward chains, calculating a switching point of the combination, forming a complete observation sequence in the transit period, and completing task planning.

Description

technical field [0001] The invention relates to the technical field of agile remote sensing satellites, in particular to a multi-target on-orbit observation method for agile remote sensing satellites. Background technique [0002] With the development of agile satellites, the attitude maneuvering ability of agile satellites is getting stronger and stronger. For emergencies, it can quickly point to a specific area through rapid attitude maneuvering, and continuously observe the mission area through regional gaze. However, the response to the mission requires real-time on-orbit planning capabilities, and timely and reasonable scheduling of satellite resources to achieve the highest possible observation benefits. A large number of point targets to be observed in a wide range are formed by wide-width payloads or other information, and the flying agile satellites obtain the position information and status evaluation information of these point targets from the ground or the inter-...
