由于苏联大部分地区交通不便,从莫斯科到海参威,都采用电缆及定向发射通信技术,耗资巨大。为此,它早就开始进行了卫星通信的实验。这对军事上亦有重要意义。首次试验在一九六五年用一颗闪电-1型通信卫星从莫斯科到海参威实现了直接电视广播。同年秋季,又通过第二颗闪电-1型卫星从莫斯科向巴黎播送了彩色电视。继 Due to the traffic inconvenience in most parts of the Soviet Union, from Moscow to sea cucumber Granville all use cable and directional launch communication technology, which is costly. To this end, it has already started experiments in satellite communications. This is also of military importance. The first experiment was a direct television broadcast from Moscow to Vladivostok in 1965 using a Lightning-1 type communications satellite. In the fall of the same year, color television was broadcast from Moscow to Paris through the second Lightning-1 satellite. Following
