Geolocation Test Engineering

Quality processes to guarantee reliable results during GNSS tests

The 3 stages of GNSS testing

Test engineering covers all the activities required to carry out measurement campaigns.

They can be groouped into 3 stages:

  • Preparation of test campaigns
  • Production of test data
  • Utilisation of test data

This service is based on proven skills in the fields of geolocation and (legal) metrology. The services provided guarantee the conditions for successful measurements and they are particularly justified when the issues are real.

GNSS test objectives

Test engineering is the foundation on which the services offered by the GUIDE laboratory are based. Your organization will derive decisive benefits for your own activities:

  • Secure your industrial and commercial investments with efficient solutions that respond to your customers’ requirements
  • Validate and position the performance of your solutions by tests carried out by a specialized laboratory – you can stand out from your competitors with their unfounded claims
  • Reduce your development time
  • Manage your high-performance solutions, in particular by optimizing the efficiency of your designs
  • Compare the performance of your solutions, from one version to another, from one configuration to another, from one of your models with that of another manufacturer, etc.


Test operations are engineered so as to offer services with the following advantages:

  • Validated test methodologies ensuring traceability of results and reproducibility/repeatability of measurements. European standards in particular applied. The standards EN16803-1, -2, -3 summarize best practices and the consensus of experts in the field
  • Precise and reliable measurements from instruments and solutions under test
  • Diagnostics based on guaranteed and precise analyses
  • Representative test campaigns carried out in conditions and environments similar to those encountered by your customers
  • Responding to the needs of established markets or those in the process of becoming so.
