Analytic calculation method suitable for geostationary satellite fixed point control planning

Abstract

The invention relates to an analytic calculation method suitable for geostationary satellite fixed-point control planning, which is specifically implemented according to the following steps: 1, establishing a fixed-point capture orbit control model, and determining a control target variable and a design variable; 2, establishing a fixed-point capture control terminal constraint model according to the fixed-point capture orbit control model; 3, determining a three-pulse constraint model according to the fixed-point capture orbit control model and the fixed-point capture control terminal constraint model, and obtaining the size and the control time of three pulses through calculation; and 4, determining a three-pulse control parameter meeting a terminal condition under a full perturbation condition by using a perturbation iteration method. According to the method, the three-pulse constraint model is established through the fixed-point capture orbit control model and the fixed-point capture control terminal constraint model, all possible working conditions of fixed-point capture control can be covered through three conditions, the iteration process is simple, the target value can be converged through 2-3 times, the process is simple, and the calculated amount is small.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation information processing, and relates to an analytical calculation method applicable to geosynchronous satellite fixed-point control planning. Background technique [0002] Geosynchronous orbit satellites need to perform fixed-point capture control before entering the working orbit. The orbital height, orbital eccentricity, size and direction, and fixed-point position all meet the requirements, which is essentially an in-plane three-pulse orbit transfer problem. How many times are there fixed-point capture controls, when are they carried out, whether the control times and control timing can be adjusted, and understanding and grasping the distribution of follow-up controls can enable task personnel to make reasonable arrangements for follow-up work. The basic idea of ​​fixed-point acquisition control is: within the existing longitude deviation, set the longitude drift rate of the satelli...
