Embodiment Construction

[0025] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0026] Such as figure 1 , 2 As shown, a micro-satellite large area array wide-area multi-mode staring imaging control method includes the following steps:

[0027] S1, determine the attitude reference of multi-mode gaze imaging;

[0028] S2, performing attitude maneuver path planning for multi-mode staring imaging;

[0029] S3, performing gaze imaging attitude control.

[0030] The attitude reference of the multi-mode staring imaging includes: the attitude reference of the ground mode, the attitude reference of the sun mode and the attitude reference of the ground staring imaging.

[0031] Pose Benchmarks for Multimodal Gaze Imaging:

[0032] The attitude reference of the ground mode adopts the spacecraft orbital coordinate system, O 0 is the center of mass of the satellite, O 0 Z 0 Pointing to the center...

Abstract

The invention discloses a method for controlling large-area-array wide-area multimode staring imaging of a microsatellite. The method includes: S1, determining an attitude reference for multimode staring imaging; S2, planning an attitude maneuver route for multimode staring imaging; S3, controlling a staring imaging attitude. The method for controlling large-area-array wide-area multimode staring imaging of the microsatellite has the advantages that pointing accuracy and tracking accuracy for quick staring imaging of the microsatellite can be improved remarkably, and strong approaches can be provided for quick information acquisition of various sudden disasters and continuous disaster monitoring.

Description

technical field [0001] The invention relates to a spacecraft attitude control technology, in particular to a wide-area multi-mode staring imaging control method of a micro-satellite large area array. Background technique [0002] With the development of space science and technology, there is a demand for multi-frequency, dynamic continuous observation of designated areas or targets around the world. Existing solutions can basically be divided into high-orbit staring imaging and low-orbit staring imaging. The high-orbit staring imaging mode requires the deployment of large-scale high-performance imaging satellites in geosynchronous orbits, which faces great technical difficulties and cost. The low-orbit staring imaging mode needs to establish a low-orbit low-cost ground staring network, and achieve ground staring imaging through attitude maneuvering and tracking. It has significant advantages such as low cost, high resolution, and low technical difficulty. Earth observation...
