At All Sat Communications we provide satellite phones on all 4 consumer satellite networks.
Connections are post paid through Pivotel, providing your sat phone with an Australian mobile number.
This provides you with no complicated dialling out and callers calling you are only charged for a mobile call.
Individual phone descriptions are available at our online store here.
A quick rundown on how these consumer Satellite networks work.
Using a constellation of LEO (Low Earth Orbiting) satellites and ground stations, Globalstar offers exceptional voice quality. Service is slightly degraded towards the equator as the Earth is much larger in that region and the distance between satellites is also greater so one may move out of view before another is within view which may result in call drop outs. Basically one of the satellites has to see you and a ground station to pass call data through. There are 3 ground stations in Australia in Mt Isa, Dubbo and Meekatharra.
Using 3 satellites in a geosynchronous orbit (almost geo stationary – means they stay in one spot) and covers most of the Earth – except for the poles. In Aus we use 1 satellite which is at 143.5° east, basically above PNG. So long as you have a clear view in that direction, then you will have coverage.
Using a constellation of 66 LEO (Low Earth Orbiting) satellites, Iridium has complete global coverage. Calls are routed from satellite to satellite to a ground station in Arizona then to the number called. Coverage may degrade a little towards the equator.
Thuraya uses 2 satellites in a geosynchronous orbit for the consumer network. Only covering 2/3 of Earth, Australian consumers use the satellite Thuraya 3 located at 98.5° E longitude (roughly above Singapore). So long as you have a clear view towards that direction you will have coverage.
