The above information refers in each case to the center of the country / region.
For Thuraya and Inmarsat we have indicated the elevation angle to the satellite and the azimuth. The flatter the satellite is above the horizon, the more difficult the reception will be depending on topography and buildings. This should clarify our classification. For fixed installations, the elevation angle is not crucial as long as the antenna has a clear view to the satellite.
Iridium has orbiting satellites. Here the proximity to the equator plays the decisive role, because at the equator the satellite density of the Iridium network is lowest. On the sea, however, this is negligible because there is a clear view all around, even to satellites located flat above the horizon.
Our recommendation
For the countries Kazakhstan, Mongolia and North China in mountain regions an Iridium phone is the better choice, because due to the topography a free line of sight to the Inmarsat or Thuraya satellite is not continuously given.
