Hispasat H36W-1, a geostationary communication satellite, will provide multimedia services to Europe, the Canary Islands and South America. The development was a public-private partnership between the European Space Agency (ESA), the Spanish satellite operator Hispasat and the German space company OHB System AG.
RUAG Space has made a key contribution to the success of the mission by supplying products from its locations in Switzerland, Austria and Sweden. “Our significant participation in the Hispasat H36W-1 project underscores RUAG’s determination to play a major long-term role in the commercial market for telecommunication satellites in addition to our activities in institutional space programs,” says Peter Guggenbach, CEO of RUAG’s Space Division.
New SmallGEO satellite platform
Hispasat H36W-1 is based on the new, compact SmallGEO satellite platform, which was developed by OHB System AG in the frame of the ESA Advanced Research in Telecommunications Systems program, in collaboration with RUAG Space.
Beside the satellite separation system and the satellite’s central tube coming from Sweden, RUAG Space – through its Austrian facilities – provided the thermal systems, which protect the satellite from extreme temperatures with multiple-layer insulation blankets and optical solar reflectors.
From Switzerland, RUAG supplied essential mechanisms, such as the Solar Array Drive Mechanisms, which accurately align the solar panels with the sun, and rotary actuators which deploy and point the antennas with a smooth, low-vibration control system eliminating any distortion.
For the platform electronics, RUAG Space Sweden provided a new data management system which forms the digital link between the satellite and ground control. The payload management unit also includes key components by RUAG Space, including a control module and the power supply unit. For the payload, RUAG supplied antennas as well as frequency converters
