  • Asynchronous WAM with Irregular Pulse Repetition

    Radiolocation systems for aviation based on Multi-Lateration (MLAT) typically use a set of synchronised ground sensors to receive radio signals broadcast by onboard transmitters. In most cases, the sensor synchronisation in Wide Area Multi-Lateration Systems (WAM) is provided by Global Navigation Satellite System (GNSS) receivers. However, in the case of synchronisation failure, there is still a possibility to estimate the coordinates...

  • Dynamic GNSS Mission Planning Using DTM for Precise Navigation of Autonomous Vehicles

    Publikacja

    Nowadays, the most widely used method for estimating location of autonomous vehicles in real time is the use of Global Navigation Satellite Systems (GNSS). However, positioning in urban environments using GNSS is hampered by poor satellite geometry due to signal obstruction created by both man-made and natural features of the urban environment. The presence of obstacles is the reason for the decreased number of observed satellites...

  • A Target Information Display for Visualising Collision Avoidance Manoeuvres in Various Visibility Conditions

    Publikacja
    - JOURNAL OF NAVIGATION - 2015

    The paper introduces a new approach to displaying information on targets. The proposed display visualises three types of information: targets’ motion parameters (typical for target tracking), combinations of own course and speed which collide with those targets (typical for Collision Threat Parameters Area display by Lenart (1983)) and combinations of own course and speed which are not compliant with COLREGS in this case (based...

  • Evolutionary Planning of Safe Ship Tracks in Restricted Visibility

    The paper presents the continuation of the author's research on ship track planning by means of Evolutionary Algorithms (EA). The presented method uses EA to search for an optimal set of safe tracks for all ships involved in an encounter. Until now the method assumed good visibility – compliance with standard rules of the Convention on the International Regulations for Preventing Collisions at Sea (COLREGS, 1972). However, in restricted...

  • Evolutionary Sets of Safe Ship Trajectories Within Traffic Separation Schemes

    The paper presents the continuation of the author's research on Evolutionary Sets of Safe Ship Trajectories (ESoSST) methodology. In an earlier paper (Szlapczynski, 2011) the author described the foundations of this methodology, which used Evolutionary Algorithms (EA) to search for an optimal set of safe trajectories for all the ships involved in an encounter. The methodology was originally designed for open waters or restricted...

  • Planning emergency manoeuvres

    W artykule poruszono problem planowania manewrów ostatniej szansy i zmian planowanej trajektorii statku w przypadku nieoczekiwanych zachowań obiektów obcych. Wprowadzono dwie metody. Pierwsza z nich jest odpowiedzialna za monitorowanie parametrów obiektów obcych, szacowanie prawdopodobieństwa nieprzepisowego zachowania i aktualizację trajektorii statku własnego. Druga to narzędzie wizualizacyjne umożliwiające nawigatorowi szybki...
