Heading-determination using the sensor-fusion based maritime PNT Unit

This paper presents the heading determination technique with the concept of DLR maritime PNT Unit. By analyzing the characteristics of individual existing heading sensors, a sensor-fusion based heading-determination system according to the concept of DLR maritime PNT Unit is introduced. This system improves the accuracy as well as the continuity of the heading and attitude results compared to the individual sensors. The preliminary results from a measurement campaign are presented to evaluate the performance of individual sensors and the PNT Unit.
