RUAG Space dispenser placed 250th OneWeb satellite in orbit

On Thursday, additional OneWeb satellites launched from the Russian spaceport Vostochny. A dispenser from RUAG Space placed the 36 satellites in orbit, bringing the satellite fleet to 254....

On Thursday, July 1, OneWeb launched 36 additional broadband internet satellites aboard a Soyuz launch vehicle from the Vostochny Cosmodrome in Russia. OneWeb is building a communications network with a constellation of low-Earth-orbit satellites that will deliver internet access around the world. With the further satellites in orbit OneWeb will be able to offer high speed internet connectivity to all regions north of the 50 degrees latitude before the end of the year, delivering low latency connectivity to Alaska, Canada, Greenland, United Kingdom, and Northern Europe.

More than 250 OneWeb satellites deposited
As a key supplier to OneWeb’s manufacturing factory, Airbus OneWeb Satellites, RUAG Space built the satellite dispenser, which functions as an interface between the Soyuz rocket and satellites. The dispenser will deposit the 36 satellites safely into space, bringing the constellation in orbit from currently 218 to 254. “Our dispenser is super-light and includes state-of-the-art technology to safely place the satellites in orbit,” says Holger Wentscher, Senior Vice President Product Group Launchers at RUAG Space. Airbus OneWeb Satellites—a joint venture between OneWeb and Airbus—is OneWeb’s industrial partner and leads the design and manufacturing of OneWeb’s fleet of satellites. The RUAG Space dispensers for OneWeb are built in Linköping, Sweden. Each dispenser has a 1.7 metre central cylinder structure and a height of 5.5 metres.

Satellite back-bone from RUAG Space
RUAG Space also manufactures the OneWeb satellite back-bone (structure) in Titusville, Florida. The structures are manufactured using the Automated Potting Process, a production method that uses a pick and place machine to rapidly position special inserts filled with adhesive into the satellite structure’s sandwich panels.

Thermal insulation and transport containers
In Austria, RUAG Space produces the multi-layer thermal insulation which protects the OneWeb satellites against the cold and heat in space from approx. minus 150°C to plus 150°C (-238 degrees F to 302 degrees F). The insulation consists of several layers of metal-evaporated polyimide film. RUAG Space in Austria also built handle equipment and transport containers. The high-tech, custom satellite containers are used to transport the assembled OneWeb satellites from Florida to the launch sites. The containers are equipped with a specifically designed damping system and climate-control.
