Telecommunications satellite
HYLAS-4 is a telecommunications satellite owned and operated by Avanti Communications and manufactured by Orbital ATK (now Northrop Grumman Innovation Systems) that was launched by an Ariane 5 rocket on 5 April 2018.[2]
The satellite is built to provide high speed data transmission services to Africa, Latin America and Europe.[5] It is based on Orbital ATK's Star-3 Bus, delivering 64 28 GHz fixed beams covering Africa and parts of Europe. There are also four independent steerable beams that can serve Africa, South America and Europe.[6] The capacity will partially be used to allow Avanti to expand into new markets and provide growth for existing markets.[1]
The satellite was launched into geosynchronous orbit by Arianespace on an Ariane 5 rocket in its ECA variant from ELA-3 at Guiana Space Centre in French Guiana. The launch was originally planned in early 2017 but has been delayed to 21 March 2018, and then to 5 April 2018.[1][2] The satellite reached its geostationary orbital position by 19 April 2018.[7]
