    • Dead Reckoning of Dynamically Positioned Ships: Using an Efficient Recurrent Neural Network 

      Skulstad, Robert; Li, Guoyuan; Fossen, Thor I.; Vik, Bjørnar; Zhang, Houxiang (Journal article; Peer reviewed, 2019)
      When a ship experiences a loss of position reference systems, its navigation system typically enters a mode known as dead reckoning (DR) to maintain an estimate of its position. Commercial systems perform this task using ...

    • GPS Guided R/C Car: The Local Bug Test Platform 

      Wenstad, Peder (Master thesis, 2010)
      This thesis is a part of the Local Hawk student project where the overall goal is to develop a Autonomous Unmanned Aerial Vehicle (AUAV). The project was initiated by Kongsberg Defence Systems (KDS) and is developed in ...

    • A Hybrid Approach to Motion Prediction for Ship Docking— Integration of a Neural Network Model into the Ship Dynamic Model 

      Skulstad, Robert; Li, Guoyuan; Fossen, Thor I.; Vik, Bjørnar; Zhang, Houxiang (Peer reviewed; Journal article, 2020)
      While automatic controllers are frequently used during transit operations and low-speed maneuvering of ships, ship operators typically perform docking maneuvers. This task is more or less challenging depending on factors ...

    • Inertial Navigation aided by Ultra-Wideband Ranging for Ship Docking and Harbor Maneuvering 

      Helgesen, Håkon Hagen; Fuglestad, t; Cisek, Krzysztof Piotr; Vik, Bjørnar; Kjerstad, Øivind Kåre; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      This article presents an inertial navigation system aided by local ranging measurements derived from an ultra-wideband system. The system consists of one onboard tag and several onshore anchors. It is motivated by the need ...

    • Quay Contact Detection for Ships using Motion Sensors and Machine Learning 

      Helgesen, Håkon Hagen; Kristiansen, K S; Vik, Bjørnar; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      Detecting when and where contact with the quay appears is an important ability for ships undergoing a docking maneuver. The motion of the quay, environmental forces, and hydrodynamic effects caused by the interaction between ...

    • Underwater Navigation of AUVs 

      Haugedal, Andreas (Master thesis, 2010)
      Designing and developing an autonomous underwater vehicle (AUV) that is capable of performing a diverse set of operations is challenging in many ways, and requires broad insight into many fields of research. This paper ...
