摘要
高分三号(GF-3)卫星是国内首颗设计寿命8年且转动惯量最大的低轨遥感卫星。与以往同类卫星相比,文章针对GF-3卫星的特点,对控制分系统的体系结构、技术方案、可靠性设计、寿命试验等方面进行了概述,重点论述了卫星控制分系统基于二级总线的轻小型化体系结构、高精度姿态全零多普勒导引技术、高精度高稳定度姿态控制技术、长寿命高可靠设计方案。根据卫星在轨运行数据,给出了控制分系统单机和系统性能指标在轨验证情况。
GF-3 satellite is first low-orbit remote sensing satellite which has 8 years of designed life and it is the maximal inertia in China.Firstly,this paper introduces technical characteristics of GF-3 satellite,and also simply presents several aspects in AOCS which include system archi-tecture,technical scheme, reliability design and the lifetest.Moreover, this paper mainly analyzes the light miniaturization system architecture,high-precision all-zero dopplerattitude guidance technology, high-precision high-stability attitude control technology, and long-life design scheme of satellite AOCS based on the second-level bus.Furthermore,this paper intro-duces the on-orbit verification on devices in AOCS and system performance index based on satel-lite on-orbit operation data.
