Orbit control method based on wheel-controlled mode

Abstract

The invention discloses an orbit control method based on a wheel-controlled mode. According to high-precision orbit freezing characteristics of a satellite in a sun-synchronous orbit, the control method combining a double-frequency global position system (GPS) and DORIS orbit determination, high-precision star sensitivity posture determination and high-precision wheel controlling is adopted in orbit controlling, satellite orbit control precision is improved, satellite high-precision orbit freezing tasks are achieved, and the orbit control method is a satellite orbit control method which is never adopted in the past. From 2011, the orbit control method is successfully applied to orbit controlling of a plurality of satellites in the sun-synchronous orbit, the orbit control precision reaches advanced levels in the world, and good effects are obtained.

technical field [0001] The invention relates to an orbit control method, in particular to an orbit control method based on a wheel control mode, belongs to the field of spacecraft orbit control, and relates to high-precision orbit control of spacecraft, attitude control and momentum management in orbit control. Background technique [0002] At present, remote sensing satellites generally use the orbit change method of ground orbit measurement and jet attitude control to realize satellite orbit control and orbit maintenance. The attitude determination method adopts the traditional medium-precision infrared attitude determination method. The orbit changing method of the attitude control in the momentum wheel carrying out the orbit changing process has not been reported.

AI Technical Summary

Problems solved by technology

[0003] As my country's remote sensing satellites have higher and higher orbit requirements, in order to meet the long-term high-precision orbit freezing and fixed-point requirements of sun-synchronous orbit satellites, the traditional jet attitude control orbit control method can no longer meet the orbit control requirements of high-precision remote sensing satellites. , so it is necessary to design a high-precision orbit control method to realize the mission requirements of long-term orbit maintenance of high-precision remote sensing satellites
