On September 4, the European environmental satellite "Sentinel-2C" is set for launch aboard a European Vega rocket from Kourou. Beyond Gravity has supplied critical components for this mission, including the satellite's onboard computer and navigation receiver.

"The opportunity to contribute essential elements to this environmental mission, which aims to enhance our understanding of climate change, is something we are proud of," said Oliver Grassmann, Executive Vice President Satellites at Beyond Gravity.

Beyond Gravity, based in Zurich, Switzerland, is a major supplier to both traditional and New Space clients. The Sentinel-2C satellite was assembled by Airbus Defence and Space at its Friedrichshafen, Germany site.

Sentinel-2 Onboard Computer and Antennas
Beyond Gravity's Gothenburg, Sweden site provided the On Board Computer for the Sentinel-2C satellite. This computer manages the satellite's platform, controls its position and orbit, ensures its overall health, and handles communications with Earth. Additionally, Beyond Gravity supplied the S-Band Telemetry, Tracking, and Command (TTC) antenna, which serves as the satellite's communication and control link, as well as the Remote Interface Unit.

Precision Positioning for Enhanced Data Accuracy
The precise positioning of the satellite, critical for the accuracy of the environmental data it will collect, is achieved using technology from Beyond Gravity's Vienna, Austria site. Currently, 25 Beyond Gravity navigation receivers are operational, determining the position of satellites for various European and international missions. Beyond Gravity's Zurich site provided Airbus with the solar array drive mechanisms, which orient the satellite's solar panels toward the Sun.

Vega Rocket Components
In Gothenburg, Beyond Gravity also produced the Vega rocket's On Board Computer, part of its Avionics System. Additionally, at its Emmen, Switzerland site, Beyond Gravity manufactured the payload fairing for the Vega rocket.
