Abstract

The present invention provides a small geostationary orbit satellite orbit transfer method and system, including: transferring the small geostationary orbit satellite from the earth transfer orbit to the geostationary orbit through three stages, specifically including: in the first stage, orbit change chemical The thruster is ignited, and the orbit change is performed by quickly raising the perigee height of the orbit to above the first height, and the domestic measurement and control arc is not less than the threshold measurement and control arc; in the second stage, the electric thruster is adjusted to the height of the orbit perigee to At the same time as the second altitude, the orbital inclination is adjusted to the threshold inclination, and the orbital eccentricity is adjusted to the threshold eccentricity to control the target to perform orbit change; in the third stage, the attitude control chemical thruster is ignited to enter the target orbit position accuracy range as the goal Perform a 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...
