An Integrity Monitoring Algorithm Design Based on Code Double Differences for Rail GNSS Augmentation Network
The work deals with introduction of GNSS (Global Navigation Satellite System) technology into the railway sector. Particularly, since the requirements imposed by the railway environment are stringent, the use of an external mean for providing integrity monitoring and augmentation is highly recommended. In this paper, we show an algorithm based on GNSS code double differences to identify and exclude multiple satellite faults by using data acquired by multiple reference stations. The simulations results carried out in this framework are presented in terms of detection probability and false alarm rate
