Infrastructure: Space Infrastructure - TSR 2018 examines global human spaceflight operations to include both the Chinese and US space stations, launch vehicles from all spacefaring nations, communications satellite constellations, PNT…
2005 – Mobile Satellite Service (MSS) Space Activities
Satellites also provide mobile telephony services. Satellite mobile telephony enables regional to near-global coverage depending on the satellite or constellation, using handsets that communicate directly with a satellite. Mobile satellite…
2005 – Fixed Satellite Service (FSS) Space Activities
Satellites have provided trunking for long-distance telephone service for decades. Most long-distance traffic is now routed over cable, avoiding the lag and other reductions in quality (such as echo) associated…
2012 – Mobile Satellite Service (MSS) Space Activities
One MSS industry leader, Iridium, is implementing a major network upgrade. In June 2010, Iridium selected France’s Thales Alenia Space as prime contractor for its second-generation satellite constellation, named Iridium…
2012 – Fixed Satellite Service (FSS) Space Activities
GEO satellites can allow a signal to be beamed over a wide fixed coverage area, with the potential to reach a third of the Earth’s surface. They are thus ideal…
2013 – Mobile Satellite Service (MSS) Space Activities
Another MSS industry leader is Iridium, which operates a LEO constellation of ## active satellites to provide global coverage. The Iridium constellation uses intersatellite links to route network traffic directly…
Mobile Satellite Service Orbits
The MSS sector was created to address a specific market that was underserved by FSS: maritime voice and data, enabling emergency communications for ships at sea. Subsequent MSS systems tried…
Fixed Satellite Service Orbits
GEO satellites can broadcast a signal to one-third of the Earth’s surface. They are ideal for FSS operators, who broadcast to antennas spread across several continents. Of the ## communications…
2013 – Fixed Satellite Service (FSS) Space Activities
The number of FSS satellites has grown tremendously over the past five years in response to increased demand. Deregulation of international markets has sparked the rise of new companies providing…
Orbits
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…
