In this paper, conflict probing has been proposed as an element of a UAS self separation concept. Conflict probing consists of predicting the future separation between own ship and hazards for a set of own ship velocity vectors -representing possible combinations of Track, Flight Path Angle (FPA) and …

A few years ago the Maritime Pilots Institute Netherlands (MPIN) was asked to carry out practical research aimed at developing a simple method to predict wind loads on huge constructions. For practical reasons the method should not be time consuming. Some reasons for the initiative were the following. …

Military operations, whether in the field, in the air or at sea, are characterized by their complexity, the high risks that are involved and the specialized teams who have to reach their goals under these circumstances. The improvement of high-tech equipment and the increasing complexity and uncertainty …

In the Navigation Technology Department, a special interaction exists between scientific education and research on the one hand and skill based education on the other. The skill based education consists besides theoretical courses of a lot of practical courses. The NLDA can provide their students with …

Global Navigation Satellite Systems (GNSS) currently dominate the Positioning, Navigation and Timing (PNT) community and there are no signs that this will change in the near future. But for many years the weeknesses of GNSS have been well known and besides research into GNSS a lot of research into back …

In this article a GPS inspired approach has been developed for TRN systems. The authors investigated whether the acquisition and tracking GPS concept has the potential to be applied in the TRN field with good results. The performance of the proposed system is analyzed using MATLAB simulations.The results …

Description of the evolution of navigation from a restricted field of application (nautical) and executed by a select group of navigators working in almost splendid isolation to a wide field of application (nautical, aeronautical, CRM) executed by groups of people sharing different knowledge and skills …

For the Dutch economy the ports of Amsterdam and Rotterdam are crucial. To continue the competitive positions of both ports versus foreign ports, the entrance channels to both ports have to be optimal. That said, it is however a problem. The largest ships calling at these ports have a very deep draught, …

This article discusses the revival of the interferometric positioning experiment with GPS signals that aims at measuring the three-dimensional vector between two stations. Such an experiment was carried out in the late seventies, the early days of the GPS system, almost simultaneously by two competing …

In the nineties the Delft University of Technology (TU Delft), faculty Maritime Technology (MT), department of hydromechanics, and the RNLNC, nautical sciences department, led by professor J.A Spaans, explored the possibility of determining the coefficients from full-scale sea trials. As a starting point …
