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 benches can be used to replay real trajectories, simulate disturbances or detect GNSS faults in critical applications:
- Robustness validation in constrained environments (urban, tunnel, forest).
- Tests on GNSS processing algorithms and application logic.
- Local performance mapping (HD Maps, areas with high dispersion).
- Spoofing vulnerability testing (simple and complex attacks).
PVT / IQ GNSS simulation
- Replay of PVT (Position, Velocity, Time) or IQ signals captured in the field or generated.
- Comparison of GNSS configurations or firmware.
- Simulation of satellite losses, multipath, masking, interference.
- Software-in-the-loop testing for on-board validation.
- Key applications: autonomous mobility validation, precision agriculture, railways, aeronautics, connected objects.
GNSS support and assistance
- Functional analysis of GNSS requirements.
- Definition of critical scenarios and associated test methodologies.
- Development of customised tools for signal capture and analysis.
- Integration into multi-domain campaigns (EMC, security, cybersecurity).
- Advice on the integration and validation of GNSS solutions.
Standards and accreditations
- EN 16803: reference standard for GNSS performance
- ISO/IEC 17025: COFRAC accreditation for metrological reliability
