Mobile ground segment for satellite tracking beneath the dome of the Grand Palais in Paris


Wiesbaden/Paris, 09 September 2026 – Skynopy, the French startup providing ground-station-as-a-service, has been selected by the organizing 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 centerpiece of the demonstration is a 2.4-meter 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 realizing 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.



High-tech manufacturer contributes to one of the most ambitious radio astronomy projects


Wiesbaden (Germany)/ Nevada (USA), 27 August 2026 – German antenna specialist mtex antenna technology is playing a key role in the construction of the Deep Synoptic Array (DSA), one of the world's most ambitious scientific infrastructure projects in the U.S. The completion of the observatory is scheduled for 2029; the scientific operations are expected to commence shortly thereafter. The project is funded by Schmidt Sciences as part of the Eric and Wendy Schmidt Observatory System initiative.


mtex has started the production of high-precision antenna panels for a next-generation radio telescope array developed for Caltech. The project comprises 1,650 antennas, each with a diameter of 6.15 meters, which will form one of the world’s largest radio telescope arrays. The first manufacturing steps have already begun at mtex’s production facilities in Germany, laying the foundation for the delivery of these advanced antenna systems.


The DSA represents a new generation of radio telescopes: unlike conventional observatories, the system combines the signals from all 1,650 antennas in real time, effectively operating as one radio camera. The DSA will be capable of surveying the sky approximately 100 times faster than today's radio observatories. On its very first day of scientific operations alone, researchers expect to identify around 20 million radio sources with the DSA – roughly as many as have been discovered worldwide to date.


Designed to become a world-leading platform for deep-space research, the DSA will provide new insights into the formation and evolution of galaxies and advance research into black holes, pulsars, and Fast Radio Bursts. It will also contribute to investigations of dark matter, gravity, and the structure and expansion of the Universe. Such an ambitious scientific instrument requires high-performance antenna technology combined with reliable industrial-scale production capabilities. With its engineering expertise and industrial production capabilities, mtex is contributing to the development and manufacturing of the antenna infrastructure for the DSA.


"Our work with Caltech on the final design and now the start of production of the antennas for the DSA is strong proof of our expertise in designing and manufacturing complex antenna systems,” says Lutz Stenvers, CEO of mtex antenna technology. “It demonstrates our ability to combine scientific precision with industrial-scale production and strengthens mtex’s position as an international partner for highly demanding technology and infrastructure projects."

About the DSA

The Deep Synoptic Array (DSA) will be a cutting-edge radio telescope array consisting of 1,650 dishes in a radio-quiet valley in Nevada, USA. In its five-year initial survey, the DSA will map the sky much faster than any radio telescope, current or planned, and detect over one billion sources. The array will produce images and transient alerts in real-time and will rapidly release science-ready data products to the astronomical community.


The Deep Synoptic Array aims to become the world's most sensitive radio telescope, opening new possibilities for exploring our universe. We are honored that mtex antenna technology will contribute to this groundbreaking project.
