Stellar and mtex enter into a partnership with Skynopy

09 September 2026

Skynopy, the French startup providing ground-station-as-a service, has been selected by the organising team of the International Space Summit, led by the French government, to present a live demonstration of mobile satellite tracking at the summit on 9 and 10 September 2026 at the Grand Palais in Paris. For this event, Skynopy is teaming with its two German technological partners: Stellar Professional Communication Systems (Stellar PCS) and mtex antenna technology (mtex). 

The three companies will together demonstrate a high-precision mobile ground segment capable of supporting a variety of satellite mission. The technical and visual centrepiece of the demonstration is a 2.4-metre high-precision antenna manufactured by mtex, integrated into Stellar PCS’s mobile system platform. Stellar and mtex are bringing the hardware and systems expertise to the demonstration. This includes the high-precision antenna, radio frequency (RF) technology, antenna dynamics, structural mechanics and industrial series production capacities. Skynopy completes the system with its multi mission software, network architecture and operational services.

Skynopy sells ground station access as a service: instead of building and operating their own antennas, satellite operators book contact time on Skynopy’s network through a single interface. The company’s software plans and runs each of those contacts across the whole network and delivers the data to wherever the customer needs it. At the Grand Palais, Skynopy is demonstrating that highly scalable service, which serves a wide variety of satellites and constellations.

“The demonstration highlights the importance of high-performance ground infrastructure for Europe’s technological sovereignty in space,” explains Christian Steffen, CEO and founder of Stellar PCS and co-founder of mtex. “With the rising number of satellites and constellations, there is a growing need for flexible, resilient and rapidly deployable systems that can reliably track satellites and integrate the data collected into terrestrial networks. This is what we demonstrate together with Skynopy in Paris.”

“Seeing an antenna of this calibre in action at the Grand Palais is something entirely different from a purely technical presentation,” says Lutz Stenvers, CEO and founder of mtex. “The demonstration clearly shows that high-precision ground infrastructure can now be mobile, rapidly deployable and integrated into software-defined networks. Europe needs not only high-performance systems in orbit, but also flexible and reliable infrastructure on the ground.”

“The space industry is finally realising the importance of the ground segment within the space infrastructure,” said Pierre Bertrand, CEO and co-founder of Skynopy. “In Paris we are demonstrating  our unique ground station service, collaborating with a high-tech German antenna manufacturer to leverage multiple ground stations and offer a communications service to multiple constellations through a single interface, delivering data from satellites to Earth sooner than the current state of the art. This first collaboration is a clear demonstration of how well Skynopy’s software, which orchestrates a federated network of ground stations, complements Germany’s strong communications technology industry. It is also how we intend to work in Germany, where we are building up our R&D presence and ecosystem partnerships through our German subsidiary, Skynopy GmbH.”

The collaboration behind this demonstration represents the first building block of a partnership between Skynopy, Stellar PCS, and mtex. The three companies are already working on further joint projects to offer reliable and strong European ground segment solutions.
