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 …

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 …

In this contribution the current status and future development of four Global Navigation Satellite Systems (GNSS) are reviewed. They are the American Global Positioning System (GPS), the Russian Glonass, the European Galileo and the Chinese BeiDou Compass. All four systems offer, or will offer, civil …

In the article: "Base Line Performance of the Low Cost LORADD SP Receiver" also published in "Advances in military navigation technology" the authors discussed the basic performance of the LORADD SP receiver. One of the conclusions was that eLoran in its baseline configuration cannot serve as a back …

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 …
