The Inmarsat 4-series satellites transmit over 200 spot beams to deliver strong signals to the small receivers. Each craft has a giant unfurlable antenna reflector stretching 30 by 39 feet (9 by 12 m). The new craft are 60 times more powerful and have 20 times more capacity than their predecessors, the Inmarsat 3-series of satellites. Once the F3 spacecraft becomes operational later this year, the next-generation constellation will provide global coverage for users at sea, in the air and on land.
