Our GNSS services in detail
GNSS component testing
Antennas, receivers, inertial sensors, correction modules... each component is individually tested in order to :
- Validate basic performance (gain, sensitivity, acquisition time, positioning accuracy).
- Test resilience to interference (jamming, intermodulation, EMC).
- Analyse GNSS/IMU fusion behaviour (Kalman, IA).
- Compare suppliers or configurations.
- Anticipate integration faults.
Tests carried out in controlled environments or under real constraints: extreme temperatures, vibrations, humidity, salt spray, shocks, EMC disturbances.
GNSS systems testing
Our test benches enable the re-play of real-world trajectories, the simulation of disturbances, or the detection of GNSS failures in critical use cases:
- Robustness validation in challenging environments (urban, tunnels, forests).
- Testing of GNSS processing algorithms and application logic.
- Spoofing vulnerability tests (simple and complex attacks).
- GNSS simulation
- Replay of PVT (Position, Velocity, Time) or IQ signals captured in the field or generated in the laboratory.
- Simulation of satellite losses, multipath, occlusions and interference.
- Comparison of GNSS configurations or firmware under reproducible conditions.
- Software-in-the-loop testing for on-board validation.
Each test campaign follows a rigorous metrological approach in a V-cycle (requirement > protocol > testing > processing > report).
GNSS Engineering
In addition to testing, the Emitech Group offers GNSS engineering services to analyse, model and improve geolocation performance across a region or deployment environment:
- Local performance mapping: field measurements and production of high-definition GNSS-accuracy maps, identification of areas with high signal dispersion, obstruction or degradation.
- Coverage and availability analysis according to constellations and receiver configurations.
- Environment modelling (urban canyons, tunnels, vegetation) to anticipate critical areas.
- Production of synchronised datasets (GNSS + IMU + sensors) for training AI/ML algorithms.
These engineering activities complement field trials to provide a comprehensive view of GNSS performance under real-world deployment conditions.
