About

Established in 1985 as Satellite Services B.V. (SSBV) in 2016 has been acquired by Celestia Technologies Group and re-branded to Celestia Satellite Test & Simulation B.V.  to continue as competence centre for Electrical Ground Support Equipment (EGSE) and TT&C solutions. The current workforce is around 30 employees and the annual turnover is between four  and six million Euro.

C-STS has provided the European and international space industry with modems and electrical ground support equipment for over three decades. C-STS’ systems are used in many different location and environments ranging from Institutional Laboratories, spacecraft integration and test facilities to operational Ground Stations. Having contributed to over 80% of ESA major missions, C-STS has earned an outstanding reputation in the space sector, delivering flexible and high-quality engineering, and products.

As data communication evolves, so does C-STS. With the onset of optical communications for S2G and ISL, a whole new range of products is needed, both for testing and for use in optical ground stations (OGS).

C-STS has a strong customer base, having delivered many systems to a variety of leading companies and institutions within the space industry including the European Space Agency (ESA), Airbus Defence and Space (ADS), Thales Alenia Space (TAS), OHB System (OHB), Surrey Satellite Technology Ltd. (SSTL) and many others.
