Intelligent attitude and orbit control system based on air-breathing electric propulsion

Abstract

The invention discloses an intelligent attitude and orbit control system based on air-breathing electric propulsion, and belongs to the field of spacecraft attitude and orbit control. The system is composed of an atmosphere absorption module, an intelligent adjustment module, an attitude and orbit control module, an energy supply module, an attitude execution module and a resistance compensation module. Atmospheric molecules in an orbit space are absorbed as a working medium, and then working medium supply is adjusted through the intelligent adjustment module according to the actual working medium flow rate requirement so as to support a pulse plasma thruster in the attitude execution module to carry out attitude adjustment and support a Hall thruster in the resistance compensation moduleto carry out resistance compensation and orbit transfer work. Solar panels are attached to the periphery of the system, and charging is conducted by absorbing solar energy so as to provide electric energy for all parts needing electric energy in the system. The system has the advantages that under the condition that a satellite carries a small number of working medium or even does not carry the working medium, absorbed atmosphere serves as the working medium to support various thrusters to carry out attitude adjustment and orbit transfer tasks, and working medium waste is avoided through intelligent adjustment.

Description

technical field [0001] The invention belongs to the field of attitude and orbit control of spacecraft, and specifically relates to a kind of low-carrying or even no-carrying working medium, which collects the orbital atmosphere as the working medium, and then adjusts the actual working medium flow rate requirements through intelligent control to meet the attitude adjustment and orbital requirements. Attitude and orbit control system for transfer requirements. Background technique [0002] In recent years, the number of space satellite launches has been increasing year by year. Only counting the launch plans that have been announced so far, tens of thousands of satellites will be launched in the next 10 years. However, the space orbit is a limited and non-renewable important resource. Considering that the number of satellites on the space orbit is becoming more and more saturated, in order to expand the operating range of the satellite and improve the mission capability of th...
