From a geosynchronous orbit, a satellite antenna with a beamwidth of 17.3 degrees covers the 42% of the surface of the Earth dealing with the satellite from which line of site communications are theoretically attainable. There are nonetheless some inherent inefficiencies associated with this technique of stabilisation since solely some of the photo voltaic cells can be illuminated by the Sun at anybody instant as the satellite rotates. At the identical time the satellite wants omnidirectional antennas so that at least some of the antenna’s beam is always pointing in the direction of the Earth because the satellite rotates. This leaves many of the radio wave vitality wastefully radiated into area.
Communication satellites have additionally proven to be one of the most successful industrial...Read More
