  • R. Salamon

  - Rok 2018

  The paper describes a concept of an underwater navigation system designed to determine the location and speed of its ROVs or divers. Conducted by the Department of Marine Electronic Systems at the Gdansk University of Technology for several years, research has focused on navigation systems which determine positions on the basis of Doppler shifts of echo signals reflected from a moving object. This article presents a different version...

  - HYDROACOUSTICS - Rok 2012

  The Inertial Navigation System (INS) is usually employed to determine the position of an underwater vehicles, like Remotely Operated Vehicles (ROV) and, more recently, Autonomous Underwater Vehicle (AUV). The accuracy of the position provided by the INS, which uses accelerometers and gyroscopes, deteriorates with time. An external aiding sources such as the Global Positioning System (GPS) can be employed to reduce the error growth...

  • J. Marszal

  - Polish Maritime Research - Rok 2020

  A new acoustic navigation system was developed to determine the position and speed of moving underwater objects such as divers and underwater vehicles. The path of an object and its speed were determined by the Doppler shifts of acoustic signals emitted by a transmitter placed on the object and received by four hydrophones installed at the periphery of the monitored body of water. The position and speed measurements were affected...

• An interactive system for mobile robot navigation

  Publikacja

  • K. Rudzinska
  • H. Kormański
  • M. Carlini
  • R. I. Abenavoli

  - Rok 2005

  W pracy przedstawiono interaktywny system do zdalnego sterowania robotem mobilnym zbudowany przy użyciu języka VRML. System jest wspomagany przez algorytm wyznaczania optymalnej trajektorii ruchu robota mobilnego poruszającego się w obecności przeszkód statycznych. Otoczenie reprezentowane jest przez graf nieskierowany. W metodzie wykorzystano algorytm Dijkstry.

  - TransNav - The International Journal on Marine Navigation and Safety of Sea Transportation - Rok 2013

  The article presents the client‐server approach in the navigation system for the blind ‐ “Voice Maps”. The authors were among the main creators of the prototype and currently the commercialization phase is being finished. In the implemented prototype only exemplary, limited spatial data were used, therefore they could be stored and analysed (for path-finding process) in the mobile device’s memory without any difficulties. The...

• Synthesis of autonomous underwater vehicle control system.

  Publikacja

  • P. Grymajło
  • M. Kwiesielewicz

  - Rok 2004

  Artykuł dotyczy parametrycznej identyfikacji systemu sterowania autonomicznego pojazdu podwodnego.Badania opierają sie na modelu pojazdu o 4 stopniach swobody, zrealizowanym w środowisku programowym Matlab/Simulink. Zastosowano wielowymiarowy nieliniowy regulator PID. Przedstawiono wyniki symulacji zaprojektowanego układu sterowania.
