Communications Satellites

Year: 

Constellations of communications satellites have been in use since the 1990s, and several companies are either in the midst of deploying second-generation constellations or completely new ones. Globalstar, Iridium, and Orbcomm were the first three major companies to create this type of constellation.

Telecommunications satellites include all spacecraft whose main mission is to collect, relay, or broadcast data, which may include voice, video, and other information. Depending on the type of system, communications satellites range from very small to very large satellites and can operate from all...
The FSS and MSS industries had served their discrete markets using unique capabilities, but advancing technologies and evolving market conditions have eroded much of the contrast between these two services. Terrestrial mobile telephony has expanded greatly around the world, reducing the MSS...

Communications satellites have been a crucial part of the global telecommunications infrastructure for decades. They bridge the oceans and connect continents with international telephone calls, bring live video footage of major events to television studios, and connect the major network hubs that...

Satellite communications are perhaps the most ubiquitous example of human utilization of space, and they have been a crucial part of the global telecommunications infrastructure for decades. They bridge the oceans for international telephone calls, bring live video footage of major events back to...

A satellite database compiled by Analytical Graphics, Inc. (AGI) lists 524 active communications satellites in Earth orbit.95 Of these, 241 are in a geostationary orbit while an additional 57 satellites are in geosynchronous orbit with an orbital inclination greater than 1 degree.1
Year: 2005
Currently, the Satellite Database maintained by Analytical Graphics, Inc. (AGI) shows that 536 active communications satellites are in orbit. Of these, 298 are in a geostationary (GSO) or geosynchronous (GEO) orbit.1
