Abstract

Global Navigation Satellite Systems (GNSS) is thepositioning technology of choice outdoors but it has many limi-tations to be used in safety-critical applications such IntelligentTransportation Systems (ITS). Namely, its performance clearlydegrades in harsh propagation conditions, these systems arenot reliable due to possible attacks, may not be available inGNSS-denied environments, and using standard architecturesdo not provide the precision needed in ITS. Among the differentalternatives, Ultra-WideBand (UWB) ranging is a promisingsolution to achieve high positioning accuracy. The key pointsimpacting any time-of-arrival (TOA) based navigation systemare i) transmitters’ geometry, and ii) a perfectly known trans-mitters’ position. In this contribution we further analyze theperformance loss of TOA-based navigation systems in real-lifeapplications where we may have both transmitters’ positionmismatch and harsh propagation conditions, i.e., measurementscorrupted by outliers. In addition, we propose a new robustfiltering method able to cope with both effects. Illustrativesimulation results are provided to support the discussionand show the performance improvement brought by the newmethodology with respect to the state-of-the-art.
