An Analytical Calculation Method Applicable to Geostationary Satellite Fixed-point Control Planning

Abstract

The present invention is an analytical calculation method suitable for a geosynchronous satellite fixed-point control plan, which is specifically implemented according to the following steps: step 1, establishing a fixed-point capture orbit control model, and determining control target variables and design variables; step 2, establishing a fixed-point capture orbit control model according to the Fixed-point capture control terminal constraint model; Step 3, determine the three-pulse constraint model according to the fixed-point capture orbit control model and the fixed-point capture control terminal constraint model, and calculate the size of the three-pulse and its control timing; Step 4, use the perturbation iteration method to determine Three-pulse control parameters that satisfy terminal conditions under full perturbation conditions. The invention establishes a three-pulse constraint model through the fixed-point capture orbit control model and the fixed-point capture control terminal constraint model, and can cover all possible working conditions of the fixed-point capture control through three situations, and the iterative process is simple, and it can converge to 2-3 times. The target value, the process is simple, and the amount of calculation 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 suitable for geosynchronous satellite fixed-point control planning. Background technique [0002] Before entering the working orbit, the geostationary orbit satellite needs to perform fixed-point acquisition control, which requires the orbital height, orbital eccentricity size and direction, and fixed-point position to meet the requirements, which is essentially a three-pulse orbital transfer problem in the plane. How many times the fixed-point capture control is carried out, at what time, whether the control times and control timing can be adjusted, and understanding and grasping the distribution of the follow-up control can enable the task personnel to make reasonable arrangements for the follow-up work. The basic idea of ​​fixed-point acquisition control is: within the existing longitude deviation, at an approp...
