1988年2月至3月,我所研制的两套远望号卫星通信船站和一套岸站通信终端机,参加了我国实用通信广播卫星(331-4)的发射任务,取得了圆满成功。在远征南太平洋的42天中,甲板最高温度60℃、最高风速9级、船摇14°,连续开机正常工作近1000时,设备性能稳定。在地理仰角+6°～+78°范围内,仍能保证1/15波束宽度的跟踪精度,证明了三轴跟踪体制的优越性。在全部工作过程中,卫星传输信道误码一直稳定在10~(-8)量级,因此,话音清晰畅通,计算机数据准确无误。IBS技术体制在我国是第一次使用,它的成功将为我国国内干线卫
From February to March 1988, two sets of Yuanwang Satellite Communication Station and one shore station communication terminal developed by me participated in the launching mission of China’s practical communications broadcasting satellite (331-4) and achieved great success . During the 42 days in the expedition to the South Pacific, the maximum temperature of the deck was 60 ° C, the maximum wind speed was 9, and the ship yawned by 14 °. The stable performance of the equipment was achieved when the normal working hours of successive start-up were nearly 1000 hours. In the geographic elevation of +6 ° ~ +78 ° range, can still guarantee the tracking accuracy of 1/15 beam width, proved the superiority of the three-axis tracking system. In all the work process, the satellite transmission channel error has been stable at 10 ~ (-8) magnitude, therefore, clear and smooth voice, computer data is accurate. IBS technical system is the first time in our country, its success will be our domestic backbone
