USING DELTA RANGE ON GPS POSITIONING, FAULT DETECTION AND FAULT EXCLUSION [PDF]
IFAC Proceedings Volumes, 2005 Abstract Conventionally, the well known position-velocity-acceleration (PVA) model is adopted as the dynamic model of Kalman filter for GPS positioning. However, as a moving vehicle corners at faster speeds, the conventional PVA model without using extra sensors can no longer be adequate for describing the motion of the vehicle. Thus, the positioning

Fault-tolerant relative navigation based on Kullback–Leibler divergence
International Journal of Advanced Robotic Systems, 2020 A fault-detection method for relative navigation based on Kullback–Leibler divergence (KLD) is proposed. Different from the traditional χ 2 -based approaches, the KLD for a filter is following a hybrid distribution that combines χ 2 distribution and F ...

An Efficient Fault Detection and Exclusion Method for Ephemeris Monitoring
, 2022 Abstract With multiple ground reference stations, the double differenced carrier phase (DDCP) observation can be used to detect a faulty satellite caused by an ephemeris fault, taking advantage of the residual spatial gradient. Assuming only a single satellite can be faulty at a time, it is necessary to distinguish whether the fault comes from ...

On fault detection and exclusion in snapshot and recursive positioning algorithms for maritime applications [PDF]
European Transport Research Review, 2016 Introduction Resilient provision of Position, Navigation and Timing (PNT) data can be considered as a key element of the e-Navigation strategy developed by the International Maritime Organization (IMO). An indication of reliability has been identified as a high level user need with respect to PNT data to be supplied by electronic navigation means.
