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 ...

Optimal Fault Detection and Exclusion Applied in GNSS Positioning [PDF]
Journal of Navigation, 2013 In Global Navigation Satellite System (GNSS) positioning, it is standard practice to apply the Fault Detection and Exclusion (FDE) procedure iteratively, in order to exclude all faulty measurements and then ensure reliable positioning results. Since it is often only necessary to consider a single fault in a Receiver Autonomous Integrity Monitoring ...

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 ...
