Inmarsat was set up by the International Maritime Organization (IMO) in 1979 to provide a satellite communications network that would protect the lives of mariners anywhere at sea.
Inmarsat was the first satellite operator to meet the stringent requirements of the Global Maritime Distress and Safety System (GMDSS) and the International Civil Aviation Organization (ICAO) for global safety communications.
Today Inmarsat satellite communication services are not only saving lives but empowering people and communities, enabling business and trade, and supporting humanitarian work in the most remote and challenging locations.
Inmarsat Satellite Constellation includes 14 geostationary satellites. Distinctive feature of geostationary satellites is its immobility over a targeted point above the Equator. This seeming immobility is achieved through satellite spin along circular orbit coinciding with equatorial plane, with angular speed equal to the speed of the Earth rotational rate. Herewith orbital altitude makes 35,786 km. Inmarsat satellites provide coverage of the Earth surface with latitude restrictions–76°.
