- W4310346724 abstract "The application background of high-precision directional management technology in Fengyun-4 satellite is introduced in this paper, in order to meet the requirement of “accurate pointing, stable attitude and quiet platform” for multiple high-precision remote sensing loads, the dynamic characteristic of the moving parts, the characteristic of space disturbance torque and the dynamic model of the whole satellite are studied, The attitude control system of Fengyun-4 satellite is introduced. In order to realize the precise directional control of the LOS of several remote sensing instruments, a series of directional management measures such as high-precision measurement and control of platform benchmark, geometric calibration for LOS of remote sensing instruments are put forward. It has broken through many key technologies such as precise planning and testing of satellite dynamics spectrum, high-precision measurement and determination, high-precision attitude control, image navigation and registration, micro-vibration measurement and suppression, etc. After in-orbit flight verification, all indexes meet the design requirements, and high-precision directional management of multi-view axes of onboard loads has been realized." @default.
