The Inmarsat satellite constellation consists of 13 satellites in a geosynchronous (GEO) orbit approximately 22,000 miles above the earth. The satellites are positioned to transmit radio beams in two global configurations covering the oceans and major land masses. It is important to note that Inmarsat coverage extends from latitudes of -82° to 82° regardless of longitude, so higher latitudes like the polar regions are not covered.
International travellers: Please research local laws before you travel as some countries don’t permit the use of satellite phones. For travel to India, note that local laws require airtime service be acquired from the local provider BSNL.
