Description:

• Orbital is manufacturing the HYLAS 2 GEO communications satellite for Avanti HLYAS 2 Cyprus Limited. HYLAS 2 will carry 24 active Ka-band user beams and six gateway beams, and will produce approximately 5.0 kilowatts of payload electrical power. The Ka-band spot beams will provide two-way communications services to facilitate high-speed delivery of data to end-user applications such as corporate networking, broadband Internet access, business continuity services and video distribution. Using the HYLAS 2 spacecraft, Avanti will provide its data and video services to Northern and Southern Africa, Eastern Europe and the Middle East. In addition, the spacecraft will be equipped with a steerable spot beam, also operating at Ka-band, which can provide coverage anywhere on Earth that is visible to the satellite.

Mission details:

• Launch delayed from June 2012.
• Arianespace flight VA208, probably using Ariane 5ECA launcher L564, placed two communications satellites in geostationary transfer orbit on Aug 2, 2012. Intelsat IS-20 will provide C and Ku-band comms to Asia, Africa and the MidEast, replacing IS-7.
• The much smaller Hylas 2, for Avanti Communications, will support Europe, Africa and the MidEast with Ka-band broadband communications; it is an Orbital Star-2.4E with a mass of 3311 kg full 1532 kg dry.
• By Aug 7 the payloads were in 30622 x 35780 km x 0.1 deg and 18268 x 35774 km x 1.0 deg orbits, while the ESC-A stage and SYLDA were in a 252 x 35752 km x 5.9 deg orbit.
