Fundamentals of training navigators of ships flying foreign flags when entering the inland waterways of the Russian Federation [PDF]

open access: yesE3S Web of Conferences, 2022
Navigation on inland waterways, such as rivers, canals, fairways via reservoirs and lakes is performed under conditions of a minimum under the keel clearance, hydrodynamic interaction between the ship's hull and underwater limits of the fairway, and the ...

Modeling and fault diagnosis of flat inland navigation canals [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2018
This article regards the development of an analytical redundancy-based approach for detecting and isolating both sensor and actuator faults in flat inland navigation canals. Inland navigation networks are principally used for transport and are composed of many canalized natural rivers and artificial canals characterized by no slope.

Regional Ionosphere Delay Models Based on CORS Data and Machine Learning

open access: yesNavigation, 2023
The ionospheric refraction of GNSS signals can have an impact on positioning accuracy, especially in cases of single-frequency observations. Ionosphere models that are broadcasted by the satellite systems (e.g., Klobuchar, NeQuick-G) do not include ...

Probabilistic Map Matching for Robust Inertial Navigation Aiding

open access: yesNavigation, 2023
Robust aiding of inertial navigation systems in GNSS-denied environments is critical for the removal of accumulated navigation error caused by the drift and bias inherent in inertial sensors. One way to perform such an aiding uses matching of geophysical

Extending the Real-Time Kinematics Survey Method to Global Navigation Satellite System-Denied Areas Using a Low-Cost Inertial-Aided Positioning Pole

open access: yesNavigation, 2023
The global navigation satellite system (GNSS) real-time kinematics (RTK) survey method cannot be used in GNSS-denied areas largely due to signal blockage.
