中国卫星电视系统日凌中断的现在与未来

Today and Future of Sun Outage on Satellite Television System in China

本文通过实例计算,分析了C波段卫星电视分配系统日凌中断的根本原因,预测了K波段卫星电视直播系统日凌期间不中断传输的可能性。文中给出了利用微机计算的、不同轨道位置的同步卫星在中国境内发生日凌的规律。

By means of the example calculation,this paper analysed the essen-tial reasons of sun outage on satellite-television distribution system in C-bandand calculated the probability for continuous transmission during the period ofsolar transit in k-band sa ellite-television direct broadcasting system.In thepaper,the laws of solar transit of synchronuos satellite whith various orbit-positioas in Chinese territory are presented.
