GNSS systems and components

Evaluate reliability, accuracy and robustness in a real-life environment

Satellite geolocation (GNSS) is now at the heart of embedded technologies, critical industrial applications and intelligent mobility. Whether for a drone, an autonomous vehicle, railway equipment or an IoT sensor, the integration of reliable, high-performance GNSS building blocks is a prerequisite for any secure, compliant operation.

Why test GNSS systems and components?

The Emitech Group, via its expert subsidiary GUIDE-GNSS, offers a comprehensive range of tests dedicated to the characterization and validation of GNSS systems and their components (antennas, receivers, IMUs, barometers, correction modules, etc.). Our services are aimed at design offices, validation managers, technical buyers and integrators of PNT (Position, Navigation, Timing) systems looking for objective, reproducible data.

What sectors are involved in these trials?

Automotive, rail and marine

GNSS validation of on-board systems for navigation, positioning and driver assistance, including in complex or degraded environments.

Precision agriculture, energy and industry

Optimisation of GNSS solutions for industrial, agricultural and infrastructure applications, with measurement of accuracy, continuity and signal integrity.

Aeronautics and space

GNSS performance evaluation for sensors, plotters, connected objects and intelligent mobility applications.

Defence

Checking the robustness of equipment in the face of the sector's stringent requirements.

Focus on our GNSS testing expertise

GNSS component testing

Control the performance of your antennas, receivers or sensors before integration:

Unit testing of technological building blocks: gain, radiation pattern, TTFF accuracy, IMU drift noise, etc.
Robustness tests: vibration, extreme temperatures, RF interference, salt spray, etc
Comparison of suppliers or batches, validation of compliance with specifications

Testing complete GNSS systems

Validate the overall performance of your geolocation system under representative conditions:

Positioning accuracy, continuity and integrity (metric to centimetric)
Resilience in complex environments (dense urban areas, tunnels, forests, etc.)
Dynamic assessment: convergence time, behaviour in the event of signal loss or degradation
Validation in real or simulated mode, using digital twins and advanced GNSS simulators
