Inmarsat
Inmarsat is pushing the envelope of mobile communication for thirty years, and thanks to the fleet of eleven satellites it's services are covering most of the Earth's surface.
Modern communication needs are thoroughly satisfied by Inmarsat's BGAN (Broadband Global Area Network) serviced by a constellation of three satellites. BGAN enables simultaneous use of voice and data (IP) communication. Terminals for accessing the BGAN are available in fixed and vehicle-based models, with special versions applicable in the defense industry.
Inmarsat also provides Fleet Broadband, a range of products and services tailored for communication aboard seafaring vessels. These communication systems use the same satellite constellation which powers the BGAN network, and also offer simultaneous data and voice capability. Equipment manufactured by Thrane & Thrane is among the most sought after.
Besides high-throughput communication links on land and sea, Inmarsat enables personal communication with satellite phones. A prime example is IsatPhone Pro. Designed for dust, impact and water resistance, with a high talk and standby time (8 and 100 hours respectively), IsatPhone Pro is capable of SMS and data transfer as well and network availability inside coverage area exceeds 99,9%. These qualities make it one of the most reliable communication tools available.
