Hylas 2 is a Commercial Communications Satellite that was manufactured by Orbital Sciences Corporation based in Dulles, Virginia, and will be operated by Avanti Communications Group, London. The Satellite is based on Orbital’s Star-2.4 Burs and has a liftoff mass of about 3,080 Kilograms. The Spacecraft hosts a payload of 24 active Ka-Band Transponders and six gateway beams. Total Payload power is about 5 Kilowatts. Ka-and spot beam technology provides high-speed delivery of data to end-user applications such as corporate networking, broadband Internet access, business continuity services and video distribution. The vehicle has two deployable antennas with six antenna surfaces and one steerable Nadir antenna which provides a single steerable Ka-Band Spot Beam which can provide coverage for any location in the satellite’s field of view. The Spacecraft is outfitted with two deployable solar arrays and batteries, is three-axis stabilized and has an on-orbit servicing life of 15 years. It propulsion system features an IHI BT-4 Main Engine.
BT-4 was developed by IHI Aerospace, Japan and has a dry mass of 4 kilograms and a length of 0.65 meters. The engine provides 450 Newtons of Thrust and uses Hydrazine and mixed Oxides of Nitrogen as propellants. Hylas 2 will operate from an orbital position of 34 degrees West in Geostationary Orbit providing coverage of Northern and Southern Africa, Eastern Europe and the Middle East.
