Serving Space Agencies

Space agencies are the pioneers and protagonists driving the technology developments required for the satellites and systems designed to meet the economic, scientific and practical challenges facing our planet.

The European Space Agency (ESA) is providing its support to the European Commission in leading the Copernicus Earth-observation programme and the industrial development of Europe’s EGNOS and Galileo satellite navigation systems, and has invested more than €300 million—7% of its budget—in telecommunications and integrated applications.

Telespazio France is actively involved in operating the EGNOS and Galileo programmes—through the ESP and GSOP contracts—on behalf of the European GNSS Agency (GSA) and in providing operational support for the payloads on the Copernicus programme’s Sentinel-1, Sentinel-2 and Sentinel-3 satellites—through the PDGS contract with ESA.

The French space agency CNES is a pioneer in Europe, playing a key role in these European programmes and through the Guiana Space Centre (CSG), as well as in national programmes like the initial TELECOM series of satellites and the SPOT optical Earth-observation satellites, and bilaterally with the United States, Russia, Japan and India, to name a few of its international partners.

As a historic operator of satellite systems tasked with maintaining all associated networks, Telespazio France has been working with CNES for several decades to:

  • operate technical facilities at the CSG in Kourou
  • deploy and operate satellite communications links between the CSG and most of the stations in the launcher telemetry and tracking network
  • maintain the ground station network and provide support for stationkeeping and mission operations for most of the satellites operated by CNES from its Toulouse Space Centre (CST)


"From Europe’s spaceport in Kourou, French Guiana, Telespazio France has been involved in the launch of every Ariane, Soyuz and Vega vehicle."

Telespazio is the partner of choice supporting the deployment and operation of European space agencies’ systems.

Key space industry figures:

  • €7.25 billion in revenues generated in 2014
  • 1,700 people working permanently at the Guiana Space Centre (CSG)
  • 250 launches from the CSG since 1968
  • 35,000 people working in Europe’s space industry

To support the development and operation of these institutional programmes, Telespazio France’s expert software engineers are conceiving data portals—such as ISIS, ngEO, EOLI and THEIA—and associated applications for agencies and research laboratories.

Infrastructure through-life support and operations

Through-life support (TLS) is crucial to assure the safety and availability of space infrastructures. And being able to detect technical anomalies quickly and remedy them effectively is vital.

To meet this strategic need, Telespazio France operates and maintains space infrastructures for its institutional and private customers in France and Europe.

Telespazio France has been working with CNES and Arianespace in France and French Guiana for more than 30 years.

Satellite and mission control

A satellite must be constantly controlled to:

  • check it is correctly positioned to accomplish its mission in optimal fashion
  • manage its status

The job of Telespazio France’s controllers is to watch over all of these parameters and to uplink programmed telecommands.

Its teams provide operational support for satellite control and operations for CNES and the French military​.

Telecommunications services

In the fields of telephony, the Internet, television and—more recently—connected objects, advances in telecommunications have revolutionized how we exchange data and information, making it possible to communicate over vast distances.

The Telespazio group is the world leader in satellite telecommunications, a sector written into its DNA in which it has a long heritage. In 1964, it delivered the first live TV pictures from the Olympic Games, and five years later it pulled off the same feat to show humans’ first steps on the Moon. These historic moments were made possible by cutting-edge infrastructures and notably by the global coverage afforded by the group’s 7 teleports.

Drawing on this technological heritage, Telespazio France brings its customers secure and reliable solutions all over the globe and beyond to:

  • provide coverage of underserved regions
  • set up resilient telecoms solutions in times of crisis
  • network remote sites
  • provide communications for space agencies and institutional, military or business customers



Operations and deployment engineering

Ground segments are key elements of space systems. All satellites sent into orbit need to exchange data like telemetry. To achieve this, sufficient coverage has to be assured by ground stations capable of tracking the satellites and retrieving data from them.

Through its experience operating navigation and positioning systems like Europe’s EGNOS and the Monitoring of the Environment for Security in Africa (MESA) programme, Telespazio France is an expert in maintaining and operating signal reception and processing systems.

Its experts advise institutions and conduct operations around the world, helping to deploy stations where needed and assuring continuity of service and maintenance.


Engineering and application solutions

Telespazio France combines its expertise in space and software solutions to offer ever-more-innovative tools for 3D visualization, simulation and monitoring.

The group develops support platforms for space agencies, bringing them a broad palette of solutions spanning real-time 3D visualization of telemetry, processing of geospatial data in crisis situations, decision support, libraries of tried-and-tested modules and more. The common denominator between these solutions is that they are all built around high-performance, reliable precision technologies.
