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 …

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 …

Connectivity does not automatically provide NEC, but there is no NEC without connectivity. The integration of UCSs into a C2 network can significantly reduce the amount of voice communication needed to coordinate and synchronize events. The integration of UCSs into an ATMnetwork provides the basis for …

Software-Defined Receivers (SDR) are radio receivers that contain as few hardware components as possible. In such a receiver, the signal processing block then starts as close as possible after the antenna, and is carried out with scripts running on a general-purpose processor contrary to traditional …

The enhancement of GPS technology enables the use of GPS devices not only as navigation and orientation tools, but also as instruments used to capture travelled routes: as sensors that measure activity on a city scale or the regional scale. TU Delft developed a process and database architecture for collecting …
