Configuration for low-earth-orbit remote sensing satellite and mounting method thereof

Abstract

The invention provides a configuration for a low-earth-orbit remote sensing satellite, which comprises a base plate, a middle plate, a top plate, a plurality of transverse lateral plates and upright lateral plates, wherein the base plate, the middle plate and the top plate are enclosed into a sealed space by the transverse lateral plates and the upright lateral plates; a central force-bearing cylinder is arranged in the sealed space; corresponding solar cell arrays are arranged on the two sides of the sealed space; a supporting rod is connected between the base plate and the middle plate; four isolating plates are uniformly distributed and are arranged between the middle plate and the top plate; a payload bay is connected above the top plate; and an overskirt is connected to the bottom of the base plate. The configuration for the low-earth-orbit remote sensing satellite has a stable structure, is capable of carrying a large-size and large-mass load, and is high in adaptability for the characteristics of large volume, heavy weight, high precision demand and difficulty in mounting of the present payload.

Description

technical field [0001] The invention relates to the configuration of a remote sensing satellite, in particular to a configuration of a low-orbit remote sensing satellite and an installation method thereof. Background technique [0002] A low-orbit remote sensing satellite under development, the whole satellite weighs about 1000kg, its detection load weighs 190kg, the installation surface area is 834mm × 936mm, and the flatness requirement of the installation surface is 0.05mm. [0003] For the existing comparable satellite platform configurations, it is difficult to achieve such a high-weight load-bearing requirement because the large weight and large volume load are not considered in the design, and the long-term consideration is not taken in the structural design. Moreover, the performance is unstable, the installation is difficult, and the adaptability is poor. [0004] Therefore, in order to meet the load installation requirements of the satellite weighing 190kg, includ...
