Formation layout and installation system for three-axis stabilized satellites

Abstract

The invention discloses a formation layout and installation system for a three-axis stabilization satellite. In order to meet the formation requirement for the satellite, formation thrusters need to be added to the satellite on the basis of a posture control thruster and a track control thruster; under a launching state, effective load and solar battery arrays of the satellite are drawn to the periphery of the satellite; when the satellite stays on the track, the effective load and the solar battery arrays are all spread in the Xa direction of the flight direction of the satellite to ensure that plumes of the formation thrusters do not intervene in the solar battery arrays and the effective load, and guarantee the maximization of the efficiency of the formation thrusters; according to theflight posture of the satellite, the formation thrusters are divided into two groups, the two groups are distributed at a +- Ya side of the satellite separately, the planes of the thrusters are perpendicular to the direction, pointing to the ground, of the satellite, and the formation thrusters cooperate with one another to pass through an average centroid of the satellite when the satellite staysat an on-track flight state. By adopting the formation layout and installation system, the satellite installation accuracy of the formation thrusters and the manufacturability of operation implementation are ensured; the demands of the formation thrusters for installation, accuracy measurement and formation control in the satellite can be effectively met.

Description

technical field [0001] The invention relates to the technical field of satellites in aerospace technology, in particular to a formation layout and installation system for three-axis stable satellites. Background technique [0002] Compared with a single satellite in orbit, short-distance formation satellites fly in a certain configuration and work together in orbit, which is an important means to achieve space activities such as interferometry, stereoscopic imaging, and space monitoring. Under the background that our country is currently moving from a space power to a space power and the satellite industry is booming, satellite formation technology is a strong support for the development of my country's applied satellite industry. In order to realize the formation control of a certain satellite, formation thrusters need to be arranged on the satellite to meet the requirements of satellite formation flight in orbit. Multiple attitude and orbit control thrusters have been use...

AI Technical Summary

Problems solved by technology

Multiple attitude and orbit control thrusters have been used on the surface of the three-axis stabilized satellite, which are subject to the satellite and launch vehicle installation interface, solar array configuration, payload configuration, antenna and sensor field of view, star structure and thermal control interface. As well as the constraints of the thruster plume, it is extremely difficult to achieve a reasonable and feasible formation thruster layout on the surface of the star. Therefore, it is necessary to develop a system that meets the needs of satellite formation use, has good installation and operation technology, and is suitable for the mechanics of the active section of the launch vehicle. Layout and installation technology of formation thrusters under environmental and other performance constraints

In the launch state, the satellite’s payload and solar cell array are gathered around the satellite; while in orbit, the payload and solar cell array are deployed along the Xa direction of the satellite, so the layout of extraterrestrial equipment, especially the attitude and orbit control thruster The layout causes great limitations, and the location of the large-area solar cell array and the formation thruster is relatively close, which has a great impact on the plume in the unfolded state, affecting the satellite orbit control and formation efficiency, resulting in the formation of the formation thruster on the star. Layout is extremely difficult
