Attitude and Orbit Control System Design and On-orbit Verification of New Technology Test Satellites C and D

介绍了新技术试验卫星C星、D星姿轨控分系统设计和在轨验证情况。姿轨控分系统具备任意目标凝视跟踪、条带拼接成像、主动推扫成像等姿态控制功能。通过基于操作系统的姿轨控应用软件架构设计和基于动态链接库的在轨编程设计,首次实现基于操作系统的星载应用软件并行开发。通过一个软件配置项实现双星功能,解决了双星研制周期短、工作模式复杂等问题。给出了卫星在轨运行的部分曲线和数据,可为遥感卫星姿轨控系统设计提供参考。

The attitude and orbit control system and on-orbit verification of new technology test satellites C and D are introduced.The attitude and orbit control system has the attitude control functions such as arbitrary target gaze tracking,strip stitching imaging,and active push-broom imaging.With the operating system-based attitude and orbit control application software framework design and dynamic link library(DLL)-based on-orbit programming design,the parallel development of operating system-based spaceborne application software is achieved for the first time.The double satellite function is achieved through a software configuration item,and the problems such as short development period and complex working mode are solved.Parts of the curve and data of the on-orbit satellites are given,which can provide reference for the design of the attitude and orbit control system for remote sensing satellites.
