Road Navigation System Monitoring Using a Pseudorange Snapshot Test
Résumé
Global Navigation Satellite Systems (GNSS) are often used to localize a receiver with respect to a given map. This association problem, also known as map-matching, is usually addressed using estimated positions computed by the GNSS receiver. This paper focus on the use of GNSS raw data (L1 pseudo-measurements) and cartographic data provided by a digital road network. Using the positioning residuals of map-aided GNSS, a new method for tackling the underlying problem of the road selection is proposed. This paper show that this approach is also well adapted to integrity problem of map-matching, since a consistency test is derived. Experimental results illustrate the performance of this method with different maps.
