Multi-target on-orbit observation method for agile remote sensing satellites

Abstract

The invention provides an agile remote sensing satellite multi-target on-orbit observation method. The agile remote sensing satellite multi-target on-orbit observation method includes: acquiring multi-target latitude and longitude information, observation weight and observation starting point information as input conditions for task planning; In the forward observation, several consecutive targets in the forward observation are combined into a forward observation sequence, forming multiple forward chains, and in the backward observation, several consecutive targets in the backward observation are combined into a backward observation Sequence, forming multiple backward chains, according to the income of different combinations of forward chains and backward chains, combined with the attitude maneuver cost generated by the observation direction, determine the combination of forward chains and backward chains, and according to the forward chain The combination of the chain and the backward chain adjusts the number of targets on the forward chain or the backward chain, calculates the switching point of the combination, forms a complete observation sequence during the transit, and completes the mission 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-...
