自1963年发射第一颗地球同步轨道通信试验卫星到1982年底,世界各国共发射了148颗同步通信卫星,从1983年到1990年代初,世界各国还计划发射160多颗同步通信卫星。本资料列出了目前仍在同步轨道上工作的和近期即将发射的200多颗通信广播卫星及其主要性能参数。(见表1—4)因苏联 Since 1963, the first test satellite for geostationary orbit communication was launched. By the end of 1982, a total of 148 synchronous communications satellites were launched in all countries in the world. From 1983 to the early 1990’s, more than 160 simultaneous communications satellites were also planned to launch in all countries in the world. This document lists over 200 communications and broadcasting satellites that are still geostationary or near-to-be launched and their key performance parameters. (See Table 1-4) For the Soviet Union
