Nautical Systems



ARPA Deneb 250
Measurement campaign at the research vessel DENEB
The Research activities of the working group “Nautical Systems” are focussed on the development of algorithm, methods, and techniques to increase the accuracy and integrity of position, navigation, and time data (PNT) for “safety-of-life” applications.These cover the application of Ground Based Augmentation Systems (GBAS), adaptive navigation algorithms and data fusion based techniques, respectively. GBAS rely on the self-validation of received navigation signals of operative GNSS and the provision of augmentation, correction, and integrity data in real time to the users. The basis for the experimental validation of GBAS in aviation (Research Airport Braunschweig) as well as seafaring (Research Port Rostock) is the Experimentation and Validation Network (EVnet) developed by the Institute itself. An integrative utilization of GNSS, augmentation systems, and other aboard sensors is necessary to achieve the complete and reliable provision of PNT data. With the gained measurement redundancy either the accuracy of PNT data can be increased or their integrity assessment can be achieved. The traffic carrier specific provision of PNT data and their integrity assessment require an application orientated development in relation to identified user needs, considered standards, and available aboard sensors. The conceptual development of the “Integrated PNT System” for the maritime traffic, the provision of enhanced components and their utilisation for traffic surveying and nautical assistance systems are key elements of the new research area “Maritime Traffic Engineering” and assigned projects.
