A survey on terrain based navigation for AUVs [PDF]

, 2010
Terrain Based Navigation (TBN) is a method rootedto the early cruise missile navigation systems, when GPS wasnot yet available. For decades, TBN has been applied as acomplementary system to INS navigation for Unmanned AerialVehicles (UAV).

Coarse Alignment of Marine Strapdown INS Based on the Trajectory Fitting of Gravity Movement in the Inertial Space

Sensors, 2016
A ship experiences the random motion of sea waves during its travels. Hence, the coarse alignment of the marine strapdown Inertial Navigation System (INS) suffers from rocking disturbances such as pitch and roll. In this paper, a novel approach of marine

High Wind Speed Inversion Model of CYGNSS Sea Surface Data Based on Machine Learning

Remote Sensing, 2021
In response to the deficiency of the detection capability of traditional remote sensing means (scatterometer, microwave radiometer, etc.) for high wind speed above 25 m/s, this paper proposes a GNSS-R technique combined with a machine learning method to ...

Proposal of Optimal Operation in Ship Rolling Motion Considering Sea State Conditions

Journal of Marine Science and Engineering, 2022
Most of the research on ship rolling motion concerns a specific type of ship, such as containerships, or analyzes sailing during certain wave characteristics, rather than the full spectrum of waves that can be encountered during the entire sea route.
