    • Formation Path Following Control of Underactuated USVs 

      Eek, Åsmund; Pettersen, Kristin Ytterstad; Ruud, Else-Line Malene; Krogstad, Thomas Røbekk (2021-06-30)
      This paper proposes a formation control method for two underactuated unmanned surface vessels (USVs) to follow curved paths in the presence of ocean currents. By uniting a line-of-sight (LOS) guidance law and the ...
    • An Integral Line-of-Sight Guidance Law with a Speed-dependent Lookahead Distance 

      Syre Wiig, Martin; Pettersen, Kristin Ytterstad; Ruud, Else-Line Malene; Krogstad, Thomas Røbekk (2018)
      This paper presents an algorithm that makes an underactuated marine vehicle follow a straight line path while in the presence of a constant ocean current. When following the path, the vehicle maintains a desired surge speed ...
    • LandX20 Experiment Report – experiment for future land warfare capabilities with focus on increased situational awareness and unmanned systems 

      Mathiassen, Kim; Baksaas, Magnus; Dyrdal Idar; Eikanger, Brage Gerdsønn; Gulbrandsen, Fredrik; Gusland, Daniel; Larsen, Martin Vonheim; Mentzoni, Eilert; Minos-Stensrud, Mathias; Moen, Jonas; Nilssen, Eivind Bergh; Nummedal, Olav Rune; Nygaard, Tønnes; Rolfsjord, Sigmund; Simonsen, Aleksander; Thoresen, Marius; Bakstad, Lorns Harald; Bentsen, Dan Helge; Eggesbø, Christian; Grimstvedt, Eirik Skjelbreid; Haavardsholm, Trym Vegard; Halsør, Marius; Hoelsæter, Øistein; Kolden, David; Krogstad, Thomas Røbekk; Macdonald, Robert Helseth; Nielsen, Niels Hygum; Nonsvik, Guri; Ruud, Else-Line Malene; Seehuus, Rikke Amilde; Wiig, Martin Syre; Østevold, Einar (2022-03-21)
      LandX20 was a collaborative experiment and demonstration where four research projects from the Norwegian Defence Research Establishment (FFI) participated. The goal of the experiment was two-fold. The first goal was to ...
    • Towards simulation-based verification of autonomous navigation systems 

      Pedersen, Tom; Glomsrud, Jon; Ruud, Else-Line Malene; Simonsen, Aleksander; Sandrib, Jarle; Eriksen, Bjørn-Olav Holtung (2020-09)
      Autonomous ships are expected to change water-based transport of both cargo and people, and large investments are being made internationally. There are many reasons for such transformation and interest, including shifting ...
