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

Using isocyanate-functionalized Kraft lignin as a reactive macromonomer for the preparation of polyurethane foams by a prepolymer technique is a well-known strategy to incorporate the biomacromolecule into a higher value polymer material. However, as

To improve the reactivity of lignin for incorporation into high value polymers, the introduction of amines via Mannich reaction is a commonly used strategy. During this functionalization reaction, intra- as well as intermolecular lignin–lignin cros

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

This work presents a novel approach for integrity monitoring of AIS data. Currently, the AIS is a valuable source for maritime traffic situation assessment but not suited for collision avoidance, as it is prone to failures and not capable of indicati

This paper discusses the advances and measurement results of a far field test range for SatCom On-the-Move terminals in Ilmenau, Germany. The test range can be operated in Ku and Ka-band, offering a complete emulation of the conditions typically met
