Multisatellite Tracking GNSS Receivers in Multipath Environments

摘要: In global navigation satellite systems (GNSS) multipath propagation potentially leads to performance degradation and a reduced robustness of the receivers. Existing algorithms aiming at reducing impact have an increased computational complexity as they typically require least additional correlators. On other hand multisatellite tracking provide high in fading environments. But their behavior is not documented yet. Therefore this paper aims comparing three different signal approaches simulated realistic environment: state-of-the-art scalar loops, vector delay locked loops joint loops. The results show benefit carrier usage tracking. both, Thus receivers prove be robust yet precise tool for standalone position estimation with GNSS signals.
