GiSAT-1

GiSAT-1 is a high-throughput geostationary communications satellite project by Global IP Cayman. It was to be designed and manufactured by Boeing on the Boeing-702MP platform. It is intended to serve 35 Sub-Saharan countries on the Ka band and offer over 150 Gbit/s of bandwidth with a flexible digital payload. It was expected to be launched in the fourth quarter of 2018.[1]

Satellite description

GiSAT-1 was being designed and manufactured by Boeing on the Boeing 702MP satellite bus. It was estimated to have a launch mass of 6 tonnes (13,000 lb) and a design life of more than 15 years.[2]

It was to be powered by two wings, with four panels each, of triple-junction GsAs solar cells providing a total of 15 kW.[2]

It was to have a fully digital high-throughput Ka band payload offering over 150 Gbit/s of bandwidth. It should offer its services in all the African continent and have four gateways in Europe for connectivity.[3]

History

On September 12, 2016, Boeing announced another win for its Boeing 702MP platform, with the order of GiSAT-1 from the start-up Global IP Cayman. It would be a 6 t (6.6 tons) satellite with 15 kW of power generation with a fully digital high-throughput Ka band payload offering over 150 Gbit/s of bandwidth. It was at the time expected to be launched in 2019.[2][4][3]

On April 3, 2017, Global IP Cayman announced that it had signed an agreement with SpaceX to launch GiSAT-1 on a Falcon 9 rocket.[1]

On December 6, 2018, Boeing announced that it was cancelling the satellite order. According to informations of the Wallstreet Journal, Boeing intends to resell the nearly complete satellite to another customer.[5]
