Satellite Navigation

Cospas-Sarsat / SAR Galileo EGNOS Galileo Emergency warning Satellite

Every day, millions of people unknowingly rely on navigation satellites to travel, communicate, or be rescued: Telespazio France contributes to these essential systems that shape our daily lives.

Our expertise covers the deployment, operation, and smooth functioning of these space infrastructures, with a shared goal: to guarantee the availability and reliability of these services, which are vital to citizen safety.

Cospas-Sarsat & SAR/Galileo

The International Cospas-Sarsat Programme is a satellite-based distress alert detection and location system operational since 1985, for which France (via the CNES) has been one of the four founding countries.

This service operates using satellites in low, medium, and high Earth orbits, with the Galileo constellation being part of the program since the very beginning of its deployment. As such, the "Search and Rescue" (SAR) service is one of the various services provided by the Galileo constellation.

Thanks to its global coverage and network, the Galileo constellation can bring new capabilities to the SAR service, such as the two-way communication service (messages transmitted to the distress beacon), the beacon remote activation service and the emergency warning service.

Telespazio France alongside CNES

Since 2018, Telespazio France has been supporting CNES in the provision of the Cospas-Sarsat and SAR-Galileo services. We handle the operation of the ground segment as a whole, ensuring its smooth day-to-day functioning and its evolution over time. Our role also covers system monitoring, anomaly management, as well as performance tracking and representation before the international community.

Our role in the SAR-Galileo services

Specifically for the SAR-Galileo services, we prepare and qualify new features, such as two-way communication with beacons.

We also support EU Member States in adopting these services and connecting them to national emergency response systems (via the ERAS platform), while ensuring the proper deployment and enforcement of all cybersecurity rules on systems connected to the Galileo network.

Beyond these core activities, Telespazio France also manages several design projects for the evolution of SAR/Galileo services on behalf of the European Commission, including projects such as :

SERENITY

The SERENITY project, initiated by the European Commission in 2020 and led by Telespazio France, aims at prototyping and demonstrating a planned evolution of the SAR/Galileo service, to be fully integrated into the existing Cospas-Sarsat system: the Two Way Communication Service (TWC), one of the four planned evolutions of the Return Link Service.
GRALLE

The GRALLE project, initiated by the European Commission in 2017, had the objective to define, design and demonstrate an efficient Galileo-based, low latency, reliable and highly standardized Emergency Warning Satellite Service (EWSS) to improve worldwide safety and security.
STELLAR

The STELLAR project, initiated by the European Commission in 2022 and led by Telespazio France, has the objective to prepare the introduction of Emergency Warning Satellite Service (EWSS) in the Galileo 1st Generation (G1G).

EGNOS

Since 2014, Telespazio France has been supporting EGNOS operations through EUSPA contracts: EGNOS operator and Support & Management Services.

GALILEO

Since 2018, Telespazio France has been involved in the development and operations of the Galileo Infrastructure.

Operational Support and Galileo Operations for EUSPA

Since 2022, Telespazio France has been supporting EUSPA in the operation and management of Galileo across all of the programme's European sites (GSMC, GCC, GSC, GRC, HQ). Our activities cover both the maintenance of the ground and space segments and security operations, logistics and site management, as well as the preparation and day-to-day monitoring of system operations.

Project Management Support for the Galileo Ground Segment with Thales Alenia Space France

Since 2018, Telespazio France has been supporting Thales Alenia Space France in project management for the Galileo ground segment mission (GMS). Our activities cover a range of areas, from system architecture and cybersecurity to integration, validation and qualification (IVQ), as well as reliability, availability, maintainability and safety (RAMS), and subcontractor management.

Emergency warning by satellite

Telespazio France designs early-warning solutions via satellite, in service of civil protection and the safety of European citizens.

Galileo EWSS

When disaster strikes, every second counts. The effectiveness of a population alert system isn't measured by the speed of the signal alone — it's measured by the certainty that it has been received, understood, and relayed, down to the very last metre.

Over the years, we have built solid expertise in the sovereign European satellite early warning system.

Working in close collaboration with EUSPA, the European Commission, national civil protection agencies, and long-standing partners such as EENA, Telespazio France supports the development of innovative solutions for the safety of European citizens:

SERENITY

The HELP 112 project, led by Telespazio France, aimed to define the optimal technical solution for transmitting the GNSS location calculated by a mobile phone to emergency services during a 112 call. AML (Advanced Mobile Location, ETSI TR103393), which enables the automatic transmission of a smartphone's location to emergency services during a 112 call, was selected and deployed in four pilot countries: Austria, Italy, Lithuania, and the United Kingdom.
GRALLE

The WorkingAge project aims to develop the WAOW tool (WorkingAge Of Wellbeing), which seeks to improve health and well-being at work by monitoring workplace conditions using various sensors and delivering recommendations through engaging, user-friendly interfaces. In this context, a WA mobile application installed on the user's smartphone leverages several algorithms responsible for collecting and monitoring data from the different sensors.
SBAS ASECNA

Under the ASECNA SBAS Phase B project initiated in 2019, Telespazio France was involved in specifying ILS/OPS activities concerning maintenance, logistics, and obsolescence management, as well as defining the validation plan based on operational concepts and scenarios. Telespazio France also contributed to demonstrating a public warning service using SBAS satellites.
