Not to be confused with Indian satellite [GISAT](/source/GISAT) 1.

**GiSAT-1** is a [high-throughput](/source/High-throughput_satellite) [geostationary](/source/Geostationary_orbit) [communications satellite](/source/Communications_satellite) project by [Global IP Cayman](/source/Global_IP_Cayman). It was to be designed and manufactured by [Boeing Satellite Development Center](/source/Boeing_Satellite_Development_Center) on the [Boeing-702MP](/source/Boeing_702) [satellite bus](/source/Satellite_bus). It is intended to serve 35 [Sub-Saharan Africa](/source/Sub-Saharan_Africa) countries on the [Ka-band](/source/Ka_band) and offer over 150 [Gbit/s](/source/Gbit/s) of bandwidth with a flexible digital payload. It was expected to be launched in the fourth quarter of 2018,[2] but the cancellation of the construction contract by Boeing in December 2018 left the launch of the satellite uncertain.[1]

## Satellite description

GiSAT-1 was being designed and manufactured by Boeing Satellite Development Center on the Boeing 702MP satellite bus. It was estimated to have a launch mass of 6,000 kg (13,000 lb) and a design life of more than 15 years.[3]

It was to be powered by two wings, with four [solar panels](/source/Solar_panels_on_spacecraft) each, of [triple-junction](/source/Triple-junction_solar_cell) [GsAs](/source/Gallium_arsenide) [solar cells](/source/Solar_cell) providing a total of 15 [kW](/source/Watt).[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.[4]

## History

On 12 September 2016, Boeing Satellite Development Center announced another win for its Boeing 702MP platform, with the order of GiSAT-1 from the start-up [Global IP Cayman](/source/Global_IP_Cayman). It would be a 6,000 kg (13,000 lb) 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][4] On 3 April 2017, Global IP Cayman announced that it had signed an agreement with [SpaceX](/source/SpaceX) to launch GiSAT-1 on a [Falcon 9](/source/Falcon_9) [launch vehicle](/source/Launch_vehicle).[2] On 6 December 2018, Boeing announced that it was cancelling the contract, citing lack of payment. According to the [Wall Street Journal](/source/Wall_Street_Journal), Boeing intends to resell the nearly complete satellite to another customer.[1]

In October 2019, Global IP announced that it was seeking to renegotiate the contract with Boeing with the backing of a US$175 million investment from [Bronzelink Holdings](/source/Bronzelink_Holdings). The money would go towards completion of the mostly-complete satellite and fulfillment of contract payments. Because the launch order with SpaceX remains valid, GiSAT-1 will still be launched on a Falcon 9 rocket; the satellite's telemetry, tracking, and control will be managed by [Hellas Sat](/source/Hellas_Sat).[6]
