Integration of Resilient Navigation Systems for Military Ground Vehicles

Eviden and Thales are collaborating to integrate Galileo Public Regulated Service capabilities into tactical military satellite navigation receivers. This technical partnership addresses the requirement for secure vehicle positioning and timing systems within contested electronic warfare environments.

Collaboration for Electronic Warfare Resilience
The partnership addresses the vulnerability of standard global navigation satellite systems to signal jamming and spoofing during military operations. Eviden provides the hardware integration and deployment framework for the tactical receivers, while Thales supplies the secure satellite navigation modules. This division of responsibilities is required to combine established combat information system architectures with specialized cryptographic navigation technology, ensuring continuous positioning data for ground forces.

System Architecture and Receiver Configurations
The technical solution involves upgrading the Plug and Play Positioning and Timing System. The hardware is deployed in two distinct configurations. The first configuration integrates the Thales TopStar Galileo Public Regulated Service core module, which processes secure European satellite signals alongside standard open-service frequencies. The second configuration incorporates the TopStar Smart Receiver to provide active anti-jamming filtering. Both architectural variants include an integrated high-precision clock to maintain timing synchronization for tactical communication networks during periods of total satellite signal loss.

Tactical Implementation and System Integration
The receivers are deployed on military ground platforms and integrated directly into the military digital infrastructure, including the SCORPION Combat Information System and field tactical radios. This hardware provides continuous geolocation and timing data to digitized armored vehicles, logistics transport, and dismounted infantry units. The primary technical use case involves maintaining an accurate common operational picture during active electronic interference, which reduces the probability of friendly fire and ensures process stability across the command chain.

Operational Impact and System Reliability
By utilizing the encrypted Galileo Public Regulated Service, the integrated receivers reduce reliance on standard positioning networks and provide hardware-based resistance to signal spoofing. Florent Chauvancy, vice president of Flight Avionics at Thales, notes that the integration of modular navigation receivers preserves the operational ability of ground vehicles in electronic warfare environments. This structural mechanism ensures that tactical networks maintain high availability and synchronization without relying on unencrypted external data sources.
