    摘要: The system comprises at least two geosynchronous satellites (S-A, S-B) having the same elliptical orbit and the same trace on the ground. The longitudes of ascending node are displaced. The moving bodies have a vertically pointed fixed antenna. The system operates for 24 hours continuously with one or other of the satellites.
