摘要
本文叙述了中国第一颗气象卫星。这是一颗试验气象卫星,重750公斤,其主体为1.40米×1.40米×1.20米,连同展开的太阳电池阵和天线共长8.6米,高1.76米。该星运行在太阳同步轨道,高度900公里,倾角99°,周期102分钟,每天绕地球运行14圈。地面站接收到了它发回的高质量的图像资料以及轨道空间的辐射环境资料。
The first Chinese experimental meteorological satellite FY-1 was launched on 7 Sept. 1988. The main objectives of FY-1 are: testing and examining the space technologies used for this satellite and the ground manipulation as well as the application of this satellite. The sunsynchronous orbit of this satellite is near circular with an altitude of 900 km, inclination of 99°and period of 102 mine Its mass is 750kg. The mainbody is 1.2m× 1.4m× 1.4m in size and with deployable solar panels connected to the left and right side symmetrically. The length of the spacecraft is 8.6m and the height 1.76m. High-quality APT, HRPT and playback pictures has been re-ceived by the ground stations. The spacecraft is researched and devel-oped in China independantly and composed of domestic materials and components.
