Realization method of remote sensing satellite configuration for large-angle maneuvering double-side view

Abstract

The invention provides a realizing method for a large-angle maneuvering double-side-looking work remote sensing satellite configuration. The method comprises the following steps that (1) when a satellite flies in an orbit, the commonly-used work posture of the satellite is that the satellite flies in a right side-looking mode with the fixed included angle between a satellite body coordinate system and an orbit coordinate system; large-angle maneuvering is achieved by rotating around a rolling shaft, and the satellite is switched to the left side-looking flying posture with the negative fixed included angle between the satellite body coordinate system and the orbit coordinate system; and according to conditions, by conducting large-angle maneuvering around the rolling shaft, the satellite is switched to the right side-looking flying posture and the like. According to the realizing method for the large-angle maneuvering double-side-looking work remote sensing satellite configuration, flying and imaging can be achieved under the left side-looking flying mode, the effect that the visual imaging band width of the satellite relative to single-side-looking flying is increased to two times is achieved, a single pair of antennas achieve the effect which only two pairs of antennas can achieve, the capacity, covering the ground, of the satellite is greatly improved, the global revisiting time can be shortened to be half of the original global revisiting time, the average visiting time is increased by one time, the service efficacy of the satellite is greatly improved, and successful application is achieved on the remote sensing satellite.

Description

technical field [0001] The invention relates to the technical field of overall configuration and layout of satellites, in particular to a method for realizing the configuration of a large-angle mobile double-side-view remote sensing satellite. Background technique [0002] With the improvement of remote sensing satellite imaging resolution and imaging quality, the performance of satellites has been greatly improved, but with the improvement of imaging quality, the weight of antenna hardware and the size of the antenna have increased. However, the size of the antenna should not be too heavy or too large, which restricts the capability of satellites. At present, remote sensing satellites generally work in a single oblique flight mode (that is, single-side viewing mode) for imaging. [0003] For the above defects, there is no design of a large-angle mobile double-side-view satellite configuration, which can improve the satellite’s in-orbit coverage and revisit ability, improve ...
