现代战争无论是规模、突然性还是破坏性都比过去空前增大,由于对抗异常尖锐,单靠原有的通信手段难以对分布于世界各个地区的诸兵种实施跨洋过海的统一指挥和协同动作。卫星通信的应用为现代战争的通信保障开辟了一个广阔的天地。把一个装有空间自动转发器的人造地球卫星发射到3·6万公里左右的上空,作为中继站。从地面发射上去的信号经过转发器上的功率放大器放大后,转发回地面。经过卫星中间接力,地球上相距1·8
Since modern warfare is unprecedented in size, suddenness and destructiveness, it has become more difficult than ever before to rely on the original means of communication to conduct unified command and coordination across the oceans and seas across all arms and arms deployed in various regions of the world. action. The application of satellite communications has opened up a vast world for the communication and security of modern warfare. An artificial space satellite equipped with an automatic space transponder was launched over 36,000 kilometers as a relay station. The signal transmitted from the ground is amplified by the power amplifier on the repeater and then transmitted back to the ground. After satellite relay, the earth is 1.8 apart
