Mission Details

Inmarsat 5 F5

Inmarsat 5 F5 (GX-5) will be a Very High Throughput Satellite (VHTS), providing capacity across the Middle East, Europe and the Indian subcontinent. The payload will seamlessly become part of Inmarsat’s existing GX high-speed global broadband network. The combination of latest satellite technology and a focus on areas of high demand, which will drive high capacity utilisation, will together result in a very low cost per bit delivered. This new satellite will be based on the flight proven Spacebus B2 enhanced platform and will be fitted with 72 Ka-band beams. With a specified design life of 16 years, it will weigh less than 4 metric tons at launch and will offer payload power of about 6.8 kW.
