“A milestone”: Holzhausener build tanks for new space satellites

“It is a milestone for us as a company, not so much in terms of finance, but in terms of image. It has global appeal,” said Dieter Grebner, founder and managing director of Peak Technology, yesterday at a press conference in Holzhausen.

The cooperation with Airbus is part of the Galileo project, the satellite navigation system of the European Union. Because the previous models are getting on in years and are being replaced, twelve new satellites are to be built for the next generation by 2024. Airbus was awarded the contract for six and the Thales armaments company for six. Above all, Europe wants to reduce its dependence on the US-based GPS system.

In use for 15 years

Tanks made of aluminum and sheathed with carbon fibers are now being manufactured in Holzhausen. They each hold more than 150 liters of xenon. The noble gas used as fuel helps to propel the satellites into space with their launch vehicles. The ascent of the satellite and its intended orbit at an altitude of 23,000 kilometers consume 70 percent of the fuel. The rest of the fuel will be used to hold the satellite in position for the next 15 years, Grebner said. The first delivery of tanks to Airbus is to take place in the middle of next year; the satellite launch is planned for 2024.

Grebner describes the greatest challenge as the precision that production requires. “The tank is one of the most delicate parts of satellites because, unlike other parts, it is not duplicated. If it causes problems, there is no satellite navigation system.” Satellites provide data for weather forecasting, enable navigation on the ground, transmit television programs and are used for research or military purposes.

Also active in Formula 1

Peak Technology brings experience in the field of space travel to the table. Founded in 2007 by Grebner in the garage, the company today employs 125 people with a turnover of 13 million euros and an export quota of 97 percent. The Holzhausener generate two thirds of the proceeds from space travel and one third from motorsport. Peak Technology supplies components for Formula 1 cars there. Grebner sees growth potential in both markets. (Rome)
