Abstract

The invention discloses an orbit control method by utilizing the interference accumulation angular momentum self balance. The method comprises the following steps that the starting offset angular momentum is built at the starting moment of the satellite orbit control; the orbit control time Tp of the satellite by utilizing an orbit control thruster in each orbit control process is determined; and in one orbit period of the satellite, M orbit control points are uniformly selected for carrying out orbit control. After the orbit control method is adopted, the goal that the interference accumulation angular momentum generated by utilizing the orbit control thruster in the orbit semi-major axis regulating process is used for controlling the satellite orbit is realized.

Description

technical field

[0001] The invention relates to the technical field of satellite orbit control, and relates to an orbit control method utilizing disturbance to accumulate angular momentum self-balancing. Background technique

[0002] Due to the need for the normal work of the payload, the Haiyang-2 satellite must raise its orbit by 55km to the target orbit. Generally, due to the large disturbance moment during satellite orbit control, jet control is used to maintain the attitude during the orbit control process. However, the Haiyang-2 satellite-Z-axis attitude control engine is not available, and the attitude control of the star during orbit control can only be performed through the momentum wheel. At the same time, due to the impact of the engine plume on the Haiyang-2 satellite, the operation of the orbital control engine produces a large interference moment on the Z-axis direction of the satellite.

[0003] In the past, the orbit control of satellites was mostly based o...
