摘要
良好的接地设计是卫星系统性能稳定、安全可靠的重要保障。简要介绍了几种卫星上常用的接地方式,分析了国内外卫星接地现状及其原因。针对高轨卫星在轨运行环境中存在的严重的充放电效应和内带电效应,详细分析并设计了一种高轨卫星接地方案。经北斗二代导航卫星地面试验及在轨飞行验证,星上各单机工作稳定正常,该接地设计可靠有效。
Abstract
A good grounding design is very important to perform reliability and safety for a satellite system. Several usual grounding architectures of satellite are introduced in this paper. The domestic and overseas grounding status and reasons are analysed. Furthermore, for serious charging and discharging effects and internal dielectric charging effect existing in the high-orbit satellite on-orbit running environment, a new grounding architecture of high-orbit satellite is analysed and designed carefully.The ground test and on-orbit flight for beidou 2nd generation navigation satellite show that the stand-alone devices work fine and the new grounding design is effective and reliable.
