Accurate and safe positioning in the battlefield

Precise, sub-meter level positioning of personnel and vehicles, friends and foes, is a must have in military and intelligence operations. It forms the basis for every successful military mission, especially as joint fire capabilities are becoming increasingly important.

In the last decade tactical drones of all sizes and shapes have taken on the battlefield, most notably in the air but also on the ground and at sea. Their remote or automated operations also requires highly accurate and robust positioning.

When it comes to ground to ground weapons, high precision is also in high demand for target acquisition systems and ultimately for GPS-steered ammunitions which are becoming mainstream in artillery forces.

However, the precision of GPS, Galileo and other GNSS (Global Navigation Satellite Systems), with 3 to 10 meters accuracy, falls short to address scenarios with a target location error (TLE) corresponding to CE90 CAT 1 (less than 6 m deviation from target).

Furthermore, GNSS signals cannot be entirely trusted because of jamming and spoofing activities happening in and out of the battlefield.

Open & flexible Solution

To answer the battlefield and geo-intelligence requirements, Geoflex data services correct the inherent errors of GNSS hardware receivers down to centimeters or decimeters accuracy.

Geoflex services can be used with most GPS/GNSS receivers on the market (giving access to their raw data). GNSS corrections are broadcast under the RTCM standard, allowing partners to use Geoflex data within their own positioning engine. Alternatively, Geoflex can license its own positioning engine.

Geoflex service encompasses the four global constellations of radionavigation satellites (Galileo, GPS, Glonass, Beidou); this increases the opportunities of measurements in the battlefield and lowers the dependency on a single constellation.

Global, resilient, military-grade technology

The correction information produced by Geoflex includes information on the precise and corrected position of the satellites, thus providing a first level of signal’s jamming and spoofing detection by comparing this correction information with the raw observations made (and potentially deceived) of the GNSS receiver.

The correction data includes the associated variances and covariances. The measurements on the satellites are carried out individually for each satellite and for each frequency, which makes it possible to isolate any corrupted data series.

Geoflex’s control over the entire chain of production and processing of the correction data offers a huge advantage for sensor fusion. Indeed, GNSS and its associated corrections can be tightly hybridized with other sensors (inertial, odometry, lidar, etc.), adding the qualities of each of these measurement systems, to obtain a reliable and robust position.

Geoflex services are available everywhere in the world. They can use any communication channels (civilian, defense) to reach the user in the theater of operations. Furthermore, Geoflex corrections are broadcast one-way: the company never knows where its service is used.

In addition, the Geoflex solution complies with stringent cybersecurity requirements from military forces.

Lastly, Geoflex technology is 100% operated under French pavilion. The technology results of research from the French space agency CNES, the service is carried out by a French company, and Geoflex’s global reference stations network are distributed throughout the world under French governance.
