FY-1C/D极轨气象卫星及其在轨运行

简要说明了风云一号(FY-1)极轨气象卫星的总体情况。介绍了FY-1C星运行5年。D星运行2年后的测控、电源、热控、敖传、扫描辐射计和星载数据收集与分发(DCDS)分系统、有效载荷空间粒子成分监测器。以及姿控和星载计算机的在轨运行情况。在轨测试结果表明，两星的在轨运行、功能和性能符合任务书的要求。最后总结了长寿命高可靠稳定优质业务运行的FY-1C，D星的创新点、主要成绩，并给出了部分应用情况。

FY-1C/D Polar Orbiting Meteorological Satellite and Its Orbital Running

The general information of FY-1 polar orbiting meteorological satellite was introduced briefly in this paper. The orbital operation of the subsystems such as telemetry and control, power, thermo control, data transmission, scanning radiometer and spaceborn data collection and data distribution, space particle composition monitor, attitude control and on-board computer for FY-1C after 5 years running and FY-1D after 2 years running was presented. And the orbital detected results showed that the all operation, function and performance of two satellites met the certain requirement. At last, the new ideas, major achievements and partial application for FY-1C, D satellite which were long cycle life, high reliable to provide a stable application in good quality were summarized.
