Abstract

Pointing mechanism installed on GOSAT/TANSO-FTS is one of the most essential techniques to realize optimal observation patterns on the earth and a long-term operation period. In orbit, the continuous increase of angular rate sensor cable torque was occurred, and this induced the limited pointing angle operation for the along track direction. In this paper, we report reproducing experimental results for the degradation of the pointing mechanism in orbit.

面向未来敏捷指向机制的TANSO-FTS指向特性的长期变化研究
在GOSAT/TANSO-FTS卫星上安装指向机构是实现对地最佳观测模式和长期运行周期的关键技术之一。在轨道上,角速度传感器缆索扭矩不断增大,导致沿轨道方向的指向角操作受限。本文报道了轨道指向机构退化的再现实验结果。
