| summary |
The first part of the paper gives a definition of positioning in the context of road work sites and stresses the advantages offered by the new generation of positioning systems. A logical classification of these systems is also proposed. The `global positioning system' (GPS) technique, as one of the most promising techniques, is detailed. The main point of the paper is the presentation of a new test facility for positioning systems which has been set up at the `Laboratoire Central des Ponts et Chaussées' (Central Laboratory of Roads and Bridges). First, its principle is described, based on the re-construction of a 6D reference trajectory to which the measurements of the system in test are compared. Then, the operation of the facility and the post-treatment software which has been specially developed for it are described. Finally, the results of some recent studies are given, results which would have been hard to obtain without using the SESSYL facility. During the first study, the facility was used to establish an accurate time-model of the vertical error and this model allowed us to propose an innovative method for improving the vertical accuracy. During the second study, SESSYL proved its capability of differentiating several state-of-the-art GPS receivers of the same category. |
