说美国先驱者11号79年9月3日探测土星时受到苏联预警卫星无线电频率的干扰,中断传输信号45分钟。在苏联宇宙号卫星中,有些卫星的轨道参数与苏联闪电型通信卫星的轨道参数很相似,但又有所不同。通过对这些卫星轨道的分析,很清楚地看出,宇宙号中的这些卫星负有新的飞行使命,它们属于宇宙号中的预警卫星系列。 Said that the U.S. pioneer, 11 September 79, was disturbed by Soviet radio satellite satellites when it was detecting Saturn, interrupting transmissions for 45 minutes. In the case of the Soviet Cosmic Satellites, the orbital parameters of some satellites are very similar to those of the Soviet Lightning-type communications satellites, but they are different. From the analysis of these satellite orbits, it is clear that these satellites in Cosmos bear new missions of flying, belonging to the series of early warning satellites in the Cosmos.
