GUIDE GNSS - An accredited geolocation test lab

Tests solutions for your GNSS equipment

GUIDE is an accredited geolocation test lab.

It provides all types of services intended to assess, validate or certify the performance of terminals using GNSS technologies.

GUIDE uses the best suited metrology techniques to conduct tests in real or simulated environments; the tests aim to best represent the situations under consideration.

In 2018 GUIDE became a Collective Interest Cooperative (Société Coopérative d’Intérêt Collectif – SCIC) associating 6 companies and 3 experts specialized in GNSS.

Develops innovative aeronautical solutions.
Intervenes in all areas related to 3D/4D measurements.

Specialist in precise, reliable and efficient geolocation

Software for rendering synthesized environments.
Independent technology consulting company.
GNSS accuracy augmentation service.

A Center of Excellence dedicated to GNSS

Created in 2010, GUIDE comprised 12 founding members to develop a Centre of Excellence dedicated to GNSS. The resources were financed partially by the state and local authorities within the “Innovation platforms” program. The mission of this center was to provide solution developers with the instrumentation, skills and approvals necessary to engage with the most demanding satellite geolocation markets.

In the course of many projects, GUIDE has built up solid operational experience to conduct GNSS metrology tests. Its Quality Management System has been acknowledged and has obtained ministerial approval 2 years in a row for the ECOTAXE project.

Adopted by the European standard EN16803-2, the methods developed by GUIDE have proven to be scientifically sound and economically essential for certifying positioning systems on board all types of transport.

Our services

We offer 3 main types of services:


Methodologies and techniques for reliable measurements.

Specification of methods, performance of measurement campaigns, interpretation of the collected data to deliver reliable outcomes with well-estimated uncertainties.


GNSS based technologies to reliably and accurately determine geographic locations in the real-world.

Expertise in precise positioning solutions based on GNSS technologies.



Extremely important functions for safety or liability issues.

Identification of feared situations, risk ranking and evaluation of the occurrence of phenomena


GUIDE services are available in 3 types of missions :

  • Evaluate the levels of security and integrity inherent in geolocation data, in particular those for autonomous vehicles and trains
  • As an independent expert applying the requirements of European standards, characterize and validate the performance of geolocation solutions
  • Evaluate GNSS performance throughout the industrial process, from design to validation of prototypes to production (Design & Architecture, R&D, Prototyping, Production)

The skills of its engineers, experts in satellite radio navigation, extend to legal metrology dedicated to geolocation.
