只有当运载器上的激光束极精确地落到接收器上,卫星间光通信才能获得良好结果。法国航天公司已签订合同研究地面卫星与低轨道地球卫星间的光通信。第二个合同是研究两个地球卫星间的通信(例如全球性电视节目转播)。用激光通信代替传统的无线电系
Only when the laser beam on the carrier lands on the receiver very accurately, good results can be obtained with inter-satellite optical communication. Aerospatiale has signed contracts to study optical communications between terrestrial and low-Earth orbit satellites. The second contract deals with the communication between two earth satellites (for example, the broadcast of a global television program). Use laser communication instead of the traditional radio system
