[瑞士《电信杂志》1977年12月报道]美国正在进行一项有助于解决多年来给通信卫星制造商和用户带来麻烦的试验计划。通信卫星通常被送入大约35400公里高的地球静止轨道。而在这种轨道上的环境条件会受到电离层底部和磁层上部的严重影响。从磁层逃逸出来的等离子体化的气体用带电粒子轰击静止轨道上的卫星, [Telegraph magazine, Switzerland, December, 1977] The United States is conducting a pilot project that will help to solve the problems that have caused communications satellite manufacturers and users over the years. Communications satellites are usually sent to the geostationary orbit, which is about 35,400 kilometers high. The environmental conditions in this orbit are severely affected by the bottom of the ionosphere and the top of the magnetosphere. Plasmatized gases escaping from the magnetosphere strike charged satellites in geostationary orbit with charged particles,
