Satellite Internet

From 1990s, the technology has brought satellite communication system that is still used as a medium to internet (via broadband data connections). This system is very much useful to those who reside in remote areas and cannot get access to broadband connections. On the other hand, if you need high availability service then use of broadband data connection will be a good way to go.

Mainly Used by Military Personnel

Communications satellites are widely used by military personnel for variety of reasons. This technology is used for military communications applications like Global Command and Control Systems. United State’s FLTSATCOM, MILSTAR and DSCS are the satellites which are used for military purposes. NATO satellites, Skynet – UK’s satellite/s, and many others are used for Military reasons.

The basic role of communications satellites is to provide telecommunication services and are used for weather tracking, mobile phone signals, broadcasting television programs, and much more. The satellites are connected on air with earth station and transmit the signal accordingly. Geostationary orbit can be found commonly filled with such satellites.
