While FSS systems all operate in GEO, mobile satellite service (MSS) systems operate in a range of orbits. Some MSS operators have built their networks using a limited number of…2008 – Fixed Satellite Service (FSS) Space Activities
The Space Report | Infrastructure | Communications Satellites | Orbits
GEO satellites provide coverage of a wide area from a relatively fixed position, making them ideal for broadcast applications to multiple downlink sites, as well as for networking services to…2009 – Mobile Satellite Service (MSS) Space Activities
