GNSS Solutions
Validate the robustness, accuracy and integrity of your GNSS solutions
The integration of Guide GNSS into the Emitech Group means that we can offer a GNSS testing service that is unique in Europe. With the widespread use of geolocation functions in embedded systems (automotive, rail, aeronautics, defence, IoT, etc.), GNSS performance validation is becoming a key issue.
Why carry out GNSS tests within the Emitech Group?
Our services enable you to qualify the robustness, fine localization and integrity of embedded solutions under realistic and reproducible conditions.
These GNSS tests are essential for :
Ask for a quote
- Ensure reliable geolocation in complex environments (urban, tunnels, forests, etc.)
- Control position deviations induced by disturbances or the configuration of the site
- Validate critical trajectories associated with business use cases
- Assess resistance to spoofing attacks (falsified GNSS signal)
Our approach: measurement expertise for your GNSS tests
The Emitech Group offers unique expertise combining :
- rigorous metrological instrumentation that complies with EN16803 standards ;
- record & replay test scenarios using digitised real GNSS signals;
- advanced analysis tools for reliable, repeatable interpretation of results;
- a tried-and-tested, accredited infrastructure, with the option of bringing the resources in-house at your own premises.

A rigorous approach to project engineering and metrological control of your GNSS tests
Our approach is based on full metrological control (ISO 17025) and a V-cycle structured process to guarantee the traceability and repeatability of results:
- Definition of needs and use cases (Task 1)
- Specification of test methods (Task 2)
- Campaign planning (Task 3)
- Data collection in real or simulated environment (Task 4)
- Measurement Processing and Statistics (Task 5)
- Deviation Analysis and Interpretation (Task 6)
- Recommendations and certified final report (Task 7)
