Collision avoidance is one of the high-level safety objectives and requires a complete and reliable description of the maritime traffic situation. The radar is specified by the IMO as the primary sensor for collision avoidance. In this paper we study

Autonomous underwater vehicles (AUVs) have changed the way marine environment is surveyed, monitored and mapped. Autonomous underwater vehicles have a wide range of applications in research, military, and commercial settings. AUVs not only perform a

Situation awareness is understood as a key requirement for safe and secure shipping at sea. The primary sensor for maritime situation assessment is still the radar, with the AIS being introduced as supplemental service only. In this article, we prese

The size and number of vessels in the maritime domain has grown significantly over the past decades. Hence, it has become more and more important to obtain reliable information about the current traffic situation. There cannot be more than one traffi
With the introduction of the Automatic Identification System (AIS) in 2004, GNSS became a cornerstone for traffic Situation assessment in the maritime domain. In this paper we study the impact of GNSS jamming on AIS and explore means of compensating

Shape functions have been derived to describe different forms of elements, notably triangles and rectangles in 2-D, and tetrahedrons, cuboids, and triangular prisms in 3-D. There are generalised solutions for some regular node configurations, and hie
