Space and Satellite Environment
By Editor | May 8, 2009
Space is an unlimited three-dimensional medium. Space is the military “high ground.” Historically, whoever held and used the high ground had a significant advantage over his adversaries. The use of space offers the any business enhanced capabilities on the battlefield of business and provides communications, position/navigation data, early warning, weather, environmental monitoring, surveillance, and targeting capabilities. Businesses today are using space products, sometimes without even being aware of it. The effective use of space systems and products is critical to successful business global operations.
There is nothing mystical about satellites. Aside from its associated high-tech design, scientific documentation, and costly launch vehicle, a communications satellite is basically just a microwave radio relay station placed on very high “hill”. Communications satellites provide a tremendous range extension advantage for any business. Satellite terminal users within a very large area of the earth covered by a satellite’s antenna can communicate with each other directly. A single satellite can link together sites that are far beyond the range of a single terrestrial line-of-sight radio link. Satellites allow the global relaying of important information in a variety of ways, either to a single user or broadcast to many users simultaneously.
Accurate weather data is often obtainable only from satellite systems. Placing a long distance telephone call often involves a satellite transmission. Maps are routinely updated using data acquired by satellites. The business uses satellite communications primarily for voice and data, but the use of satcom is rapidly developing in other application areas to satisfy broadly ranging needs. Imagery, video teleconferencing, and global broadcast are examples of those needs.
Terrestrial communications systems, even those involving fiber optic cables, cannot duplicate certain functions for which satellites are ideally suited. Mobility and flexibility in business, and broadcast capability to deployed units in a theater are unique satellite capabilities which cannot be equaled by fiber optic cable. The integration of satellite and terrestrial networks permits maximum communications flexibility for any business.
