Abstract

The invention provides a small geostationary orbit satellite orbit transfer method and system. The method is characterized in that a small geostationary orbit satellite is transferred from an earth transfer orbit to a geostationary orbit through three stages, and specifically comprises the following steps: in the first stage, an orbit transfer chemical thruster ignites, and orbit transfer is executed by taking rapid lifting of the perigee height of the orbit to be higher than a first height and taking a domestic measurement and control arc section not smaller than a threshold measurement and control arc section as a control target; in the second stage, the electric thruster adjusts the track inclination angle to the threshold inclination angle while adjusting the track perigee height to the second height, and track transfer is executed with the track eccentricity ratio adjusted to the threshold eccentricity ratio as the control target; and in the third stage, the attitude control chemical thruster is ignited to enter the target orbit position precision range to serve as a target to execute fixed-point capture.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method and system for orbit transfer of a small geostationary orbit satellite. Background technique [0002] More than 50% of high-orbit communication satellite platforms at home and abroad use hybrid propulsion systems, such as Lockheed Martin's A2100 platform, Boeing's BSS-702MP / HP platform, Thales' AlphaBus platform, and China Dongfanghong's DFH -4 / DFH-5 platform, etc., the hybrid propulsion system represents the main propulsion technology route of high-orbit communication satellite platforms at home and abroad. [0003] Domestic and foreign high-orbit communication satellites mainly use chemical propulsion to change orbit and electric propulsion to maintain position. When the chemical propulsion orbit fails, electric propulsion can be used to complete the orbit change task at the expense of life, such as the US EHF satellite. Hybrid propulsion systems at home and abroad...
