Opis:
e-Navigation, a theme introduced but IMO to improve safety of navigation at sea, is starting to gain traction in various organizations. As the concept develops, the importance of data, both static as well as dynamic, is more and more realized. IALA and IHO, in their efforts to help making e-Navigation a reality, have agreed to propose the IHO GI Register (often known as S-100 Register) as the conceptual basis for the Common Maritime Data Structure (CMDS). Utilizing this common understanding of key players in e-Navigation arena, the IMO e-Navigation Correspondence Group has firmed up the overarching architecture, enabling a series to test beds proving the concept of integration of various data streams to enable improved communication between the stakeholders on shore or at sea. The integration of pre-composed, expert generated navigational data with real time and semi real-time data like Virtual AtoNs, Tide Gages Data or MSI transmission from VTS into a single e-Navigation display, if correctly developed, implemented and executed, will be the enabler of increased situational awareness.

Opis:
The tracking filter plays a key role in accurate estimation and prediction of maneuvering vessel’s position and velocity. Different methods are used for tracking. However, the most commonly used method is the Kalman filter and its modifications. The Alpha-Beta-Gamma filter is one of the special cases of the general solution pro-vided by the Kalman filter. It is a third order filter that computes the smoothed estimates of position, velocity and acceleration for the nth observation, and also predicts the next position and velocity. Although found to track a maneuvering target with a good accuracy than the constant velocity, Alpha-Beta filter, the Alpha-Beta-Gamma filter does not perform impressively under high maneuvers such as when the target is undergoing changing accelerations. This study, therefore, aims to track a highly maneuvering target experiencing jerky motions due to changing accelerations. The Alpha-Beta-Gamma filter is extended to include the fourth state that is, constant jerk to correct the sudden change of acceleration in order to improve the filter’s performance. Results obtained from simulations of the input model of the target dynamics under consideration indicate an improvement in performance of the jerky model, Alpha-Beta-Gamma-Eta, algorithm as compared to the constant acceleration model, Alpha-Beta-Gamma in terms of error reduction and stability of the filter during target maneuver.

Opis:
Nowadays the World Transporting System are closely interrelated with the use of integrated navigation model. There is an important need for development and implementation of the new e-navigation system to meet the requirements for increasing level of safety and environment protection, efficient navigation and control of ship’s track in all phases of the passage.
