自从1963年美国发射第一颗36150公里高度的静止轨道通信卫星后,已有138颗卫星被送入静止轨道,各国还拟向不同静止轨道位置发射约160颗静止卫星。这样便会出现发达国家与发展中国家争夺使用静止轨道和频率的问题。目前静止轨道上的卫星大部分属于美国、苏联、加拿大、日本、欧空局,或者国际通信卫星组织。虽然有些发展中国家已有卫星,如中国、 Since the United States launched the first 36,150 km geostationary orbit satellite in 1963, 138 satellites have been sent to the geostationary orbit and various countries are also planning to launch about 160 geostationary satellites to different geostationary orbit positions. In this way, there will be a question of the struggle between the developed and developing countries for the use of the geostationary orbit and frequency. Most of the satellites currently in orbit belong to the United States, the Soviet Union, Canada, Japan, ESA or the International Telecommunications Satellite Organization. Although some developing countries already have satellites such as China,
