Track vehicles and dismounted soldiers in a GPS-denied environment




The ability to accurately geolocate military vehicles and dismounted soldiers in real-time is key to enhancing situational awareness and manoeuvrability. It allows higher quality command decisions which increase operational advantage.


However, GPS technology has proven to be vulnerable or even inoperative, especially in hostile conditions and/or in urban warzone conditions.


Military operations require the capacity to locate and track by not relying only on GPS or even GNSS.





SYSNAV contributes to a number of DGA’s military programs which are subject to different classification levels. In these programs, SYSNAV develops positioning and navigation solutions for vehicle platforms and dismounted soldiers that perform in GPS-denied situations.


SYSNAV Dismounted soldier smart tracker

SYSNAV is developing, in partnership with key defense industry players, a pedestrian tracking solution allowing to locate and track dismounted soldiers  in 3D in realtime, in GPS-denied conditions such as indoors (buildings, tunnels) and outdoors (urban canyons, GPS jamming, GPS spoofing, …), with a precision <0.5% of total linear walked distance.

Developing solutions to geolocate soldiers and first responders is a core focus for SYSNAV.


Sysnav BlueForce for military vehicles

High quality grade inertial measurement units (IMUs), which are today the only true alternative to GPS, remain too expensive to be deployed across large fleets of military vehicles.


SYSNAV’s magneto-inertial solution delivers military-grade inertial performance at a previously unattainable price point. Hybridized with GNSS and other sensors, it provides assurance that localization will always be reliable whatever the external factors affecting the environment.
















SYSNAV take part in the CENTURION innpvation program to develop GNSS-denied localization for dismounted soldiers and firefighters.

With financing provided by the FRench DoD, the program is jointly led by  THALES and SAFRAN.




Organized between 2018 and 2021 by the DGA (French DOD) and the ANR (National Research Agency), the “MALIN” Challenge was about indoor localization technologies in a non-collaborative environment.


SYSNAV, in collaboration with INRIA (Data Shape team), was one of 6 consortia selected to present technologies during three test sessions carried out one year apart in a training center for firefighters. During the first edition in 2018, SYSNAV presented a prototype WATA module with real time positioning. In 2019, for the second series of tests, SYSNAV showcased the TMI-REDY module with even higher performance. Eventually SYSNAV met the challenge by delivering less than 2m of error throughout an entire 30-minute trajectory.
