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.[2] Satellite descriptionGiSAT-1 was being designed and manufactured by Boeing on the Boeing 702MP satellite bus. It was estimated to have a launch mass of {{convert|6|tonne|lbs}} and a design life of more than 15 years.[3] It was to be powered by two wings, with four panels each, of triple-junction GsAs solar cells providing a total of 15 kW.[3] 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.[5] HistoryOn 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 {{convert|6|tonne|abbr=on}} 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.[3][5] 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.[2] On December 6, 2018, Boeing announced that it was cancelling the contract, citing lack of payment. According to the Wall Street Journal, Boeing intends to resell the nearly complete satellite to another customer.[1] References1. ^1 2 3 {{cite web |title=GiSat |url=http://space.skyrocket.de/doc_sdat/gisat.htm |publisher=Gunter's Space Page |date=September 12, 2016|access-date=September 13, 2016}} [1][2][3][4]2. ^1 2 {{cite web |url=http://boeing.mediaroom.com/2016-09-12-Boeing-Communications-Satellite-to-Expand-Broadband-Services-in-Africa |title=Boeing Communications Satellite to Expand Broadband Services in Africa |date=September 12, 2016 |publisher=Boeing |archive-url=https://web.archive.org/web/20160914011816/http://boeing.mediaroom.com/2016-09-12-Boeing-Communications-Satellite-to-Expand-Broadband-Services-in-Africa |archive-date=September 14, 2016 |access-date=September 13, 2016}} 3. ^1 2 {{cite web |url=http://www.businesswire.com/news/home/20170402005120/en/Global-IP-Announces-Selection-SpaceX-Launch-150-Gbps |title=Global-IP Announces the Selection of SpaceX to Launch its 150 Gbps GiSAT-1 |publisher=BusinessWire |date=April 3, 2017 |access-date=April 3, 2017}} 4. ^1 2 {{cite news |url=https://www.wsj.com/articles/boeing-backs-out-of-global-ip-satellite-project-financed-by-china-1544142484 |title=Boeing Backs Out of Global IP Satellite Order Financed by China |newspaper=The Wall Street Journal |first1=Brian |last1=Spegele |first2=Kate |last2=O’Keeffe |date=December 6, 2018 |access-date=December 30, 2018}} }} 1 : Satellites using the BSS-702 bus |
