Avanti raised £74 million from its shareholders to build a Ka-band broadband communications payload called HYLAS 3 which is to be placed on the EDRS C satellite (European Data Relay Satellite C), a LEO Earth Observation satellite. The EDRS C satellite is one component of the European data relay system, operated by ESA. EADS Astrium (Airbus Defense & Space) was the prime contractor of the EDRS C satellite with OHB System providing the bus, while SSL/MDA was responsible for the Ka-band payload.

The HYLAS 3 payload will complement the HYLAS 1 and HYLAS 2 communications satellites already in orbit. While HYLAS 1 and HYLAS 2 are designed to serve the EMEA countries around the Mediterranean, the HYLAS 3 payload will primarily serve Africa. HYLAS 3 will have up to 4 GHz of Ka-band capacity. This will be configured across eight beams within a single steerable antenna providing flexible and high throughput connectivity across EMEA and parts of Asia. The satellite will be positioned on 31˚ East orbital location with an earth view covering Africa and the Middle-East.

OHB System and EADS Astrium signed in May 2013 a contract with Avanti for the construction of the satellite. OHB built the satellite based on their SmallGEO bus as they did for satellite operator Hispasat for their HispaSat 36W-1 satellite.

EDRS-C was planned to be launched in 2016, but was delayed to mid 2018 and then to early 2019. The launch was to be executed on an Ariane-5ECA rocket, operated by launch operator Arianespace, but in case no suitable co passenger could be found, the satellite could also fly on a Soyuz-ST-B Fregat-MT. HYLAS 3/EDRS C was finally lifted on August 6^th, 2019 in a dual launch with Intelsat 39 for satellite operator Intelsat, from the Kourou Space Port in French Guiana.

In June 2026 satellite operator SKY Perfect JSAT from Japan announce the acquisition of the HYLAS 3 satellite from Avanti. The satellite will be renamed JSAT-144D and will be operated by SKY Perfect in 2027.
