第一颗荧光屏卫星于1976年10月26日发射,并于11月11日定点在东经99°上空的地球同步轨道上。到1982年底,该系列共发射了9颗卫星。据估计,荧光屏卫星的重量约为1970公斤。星上装有一个200瓦的转发器和一个由90副小型螺旋天线组成的大天线阵,可播送一套电视节目。上行频率为6188—6212兆赫,下行频率为714兆赫,转发器带宽为25兆赫,EIRP为50分贝瓦,卫星设计寿命为1—2年。 The first fluorescent screen satellite was launched on 26 October 1976 and was fixed on geosynchronous orbit at 99o E on November 11. By the end of 1982, a total of 9 satellites were launched in this series. It is estimated that the screen satellite weighs about 1970 kg. The star has a 200-watt transponder and a large antenna array of 90 small spiral antennas that broadcast a television program. The uplink frequency is 6188-6212 MHz, the downlink frequency is 714 MHz, the transponder bandwidth is 25 MHz, the EIRP is 50 dB and the satellite design life is 1-2 years.
