Beyond Gravity Supplies Key Products for New European Navigation Satellites

Beyond Gravity (formerly RUAG Space) will deliver key products like thermal insulation, the mechanisms for solar array wings and thruster pointing, the satellite structure, and the thermal insulation to the next generation of European navigation satellites. Two more European Galileo navigation satellites were launched into space and In parallel, work on the second generation of Galileo satellites is already underway on Earth.

Two further satellites were launched on 28 April 2024 (European time), from a spaceport in Florida (USA), bringing the total number of Europe’s Galileo navigation satellites in orbit to 30. In parallel, work is underway on the next generation of Galileo. The first of a further 12 Galileo Second Generation satellites are due to be launched from 2025 onwards. Six of these satellites are being produced by the satellite manufacturer Airbus (Germany), while the other six are being built by Thales Alenia Space (Italy). “Galileo is currently the world’s most precise satellite-based navigation system. Beyond Gravity plays a key role in this project, supplying key products to both satellite builders of the second generation of navigation satellites”, says Oliver Grassmann, Executive Vice President of Satellites at Beyond Gravity.

Backbone and thermal protection

For all six satellites built by Airbus, Beyond Gravity, a leading space supplier based in Zurich, Switzerland, will supply the structure (“backbone”) and thermal insulation. The structure is being built in Zurich and serves as the chassis of the satellite. The thermal insulation is being built in Austria and will protect the navigation satellites from the plus/minus 200 degrees Celsius temperatures in space and keep them at a constant room temperature. Beyond Gravity also supplies to Airbus the solar array drive mechanisms, which point the solar arrays of the Galileo satellites in the right direction to ensure that the satellite and its payload, especially the atomic clocks, have the right amount of electric power they are requesting.

12 pointing mechanisms for electric propulsion

For the six navigation satellites built by Thales Alenia Space, Beyond Gravity’s site in Austria is supplying a total of twelve mechanisms for gimballing the electric thrusters. The electric power thrusters are needed to bring the satellites to their desired Medium Earth Orbit (MEO) altitude and orbit after the Launcher releases them at 6000 km nominal altitude.

Electronics for antenna mechanisms

For the six Galileo satellites from Thales, Beyond Gravity’s site in Vienna, Austria, produces control electronics for the antenna mechanisms that establish direct communication between the Galileo satellites.

Launch adapter

At the Beyond Gravity site in Linköping, Sweden, the company designs and produces the launch adapter, which connects the Galileo satellites to the launch vehicle. Along with the according release mechanism from Beyond Gravity the adapter places the Galileo satellites into space.
