电推进器在GEO静止卫星上的安装策略

Electric propulsion installation strategy on GEO satellite

电推进器相对于化学推进器具有高比冲、小推力、长寿命、能重复启动和高的控制精度等优点而成为各国研究的热点。随着世界范围内电推进技术的蓬勃发展,电推进器已成为同步轨道(GEO)静止卫星的南北位置保持的标准配置。电推进器在卫星上的不同安装策略对电推进器与整星之间的兼容性有着重要影响,要保证电推进器与GEO静止卫星集成后两者之间的可靠兼容。因此,研究电推进器在GEO静止卫星上的安装策略很有必要。本文研究了分别在三轴稳定卫星的太阳电池阵列上和卫星星体上安装电推进器时电推进器的安装布局,为GEO静止卫星电推进器的安装布局提供解决策略,从而为卫星结构设计提供参考。

Electric propulsion has advantages as high specific impulse, small thrust, long lifetime,repeated starting and high control precision.Electric propulsion has become the standard configuration in geostationary orbit （GEO）satellite with the rapid development of electric propulsion technology in the world.Different installation strategy influenced the compatibility between the satellite and the electric propulsion.This paper researched on the installation of the electric propulsion which were installed on the satellite and the three-axis stabilized satellite solar array.This research gives a feasible scheme for the installation strategy.
