About GNSS

Satellite constellations broadcast signals at regular intervals. These signals are received and processed by GNSS receivers.
Embedded GNSS receivers provide information about their position, velocity and the precise time at which the information was recorded.
A GNSS test campaign consists in performing tests to collect data. The quality of the results depends on the ability to exactly reproduce and repeat tests to establish and analyze statistics and make a reliable diagnostic.
First and foremost, GUIDE provides test campaigns in compliance with the ISO 17025 standard in order to assess the performance of GNSS-enabled devices.
GUIDE deploys three distinct, complementary test strategies :

  • Live testing
  • Laboratory testing using synthesised GNSS signals
  • Laboratory testing using digitalized GNSS signals recorded in the real environment




GUIDE experts are involved in many fields in which using GNSS is highly strategic. As such, GUIDE has acquired a rich, continually expanding GNSS knowledge base.
GUIDE provides you with invaluable access to this information, adapting it to your environment and specific requirements to find the answers you need.
GUIDE tailors its market analysis service to your requirements, from simple consulting to an expert report backed by an in-the-field study and testing as needed.
