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 wide-area multi-mode staring imaging of a micro-satellite large area array, comprising the following steps: S1, determining the attitude reference of the multi-mode staring imaging; S2, planning the attitude maneuver path of the multi-mode staring imaging; S3, Perform gaze imaging gesture control. The invention can remarkably improve the pointing precision and tracking precision of the fast maneuvering staring imaging of micro-satellites, and can provide a powerful way for rapid information acquisition and continuous disaster monitoring of various sudden disasters.

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...
