Abstract

A proof-of-concept demonstrator of a cooperative integrity monitoring concept, called "local integrity" and tailored to terrestrial applications, is presented in this paper. The idea is to take advantage of a collaborative Vehicular Ad-hoc NETwork (VANET) architecture in order to perform a spatial/temporal characterization of possible local degradations of Global Navigation Satellite System (GNSS) signals in an urban context. Such characterization enables the computation of the so-called "Local Protection Levels". Starting from the theoretical concepts, this paper describes the experimental validation, the implementation of the algorithm on a vehicular prototype for real-time demonstration purposes, and the obtained results from a measurement campaign. The effectiveness and the performance of the proposed approach are demonstrated in a real scenario
