How to Produce a Reference Trajectory for Studying GNSS Errors in Urban Environments

Résumé

Very active research investigations in the domain of terrestrial navigation have to face the problem to establish the true trajectory, to which relevant comparison could be made. Digital maps, despite their increasing accuracy, do not solve the problem. After a brief introduction of the general frame of the study (i.e. navigation with GPS EGNOS in urban environments), the authors present the instrumentation they set-up on board a test vehicle, based on IXSEA LandINS inertial measurement unit hybridized with kinematic GPS and odometry. The reference trajectory obtained is analysed, with the aim of qualifying its accuracy.
