Robust GNSS tracking algorithm for multipath correction

Centre National d'Etudes Spatiales CNES - 10/18/2016


This algorithm detects and e ciently corrects the phenomenon of ambiguity of the correlation function that degrades the pursuit of the BOC signals from GNSS receivers when the signal processing operations use a secondary peak, eg constrained environment as city where buildings interfere with signal reception.


- Elimination of false alarms when dealing with multipath - Improves the accuracy of GNSS receiver in constrained environment, e.g. city - Easy installation on most GNSS receivers - Applicable to all BOC signals


Innovative technology - High robustness to thermal noise and multipath - Correction seamlessly and done in a single operation - Requires only a firmware update on most GNSS receivers
