Testbed architecture for maritime cyber physical systems

Cyber physical Systems (CPS) are a key technology to enable the development of highly automated and autonomous maritime systems. The development of new complex and distributed safety-critical systems increases the challenges of testing due to a variety of Verification and Validation (V+V) methods, strictly required confidence to functional correctness of heterogenous cooperating systems and management of test data. To facilitate these efforts, suitable engineering and risk assessment methods exist which will be performed by using a test environment building the basis for putting the system under test in a controlled test setting. The maritime physical testbed LABSKAUS is per definition a CPS and implements components such as a research boat, sensor infrastructure and a reference waterway as part of an overarching testbed approach for virtual to physical tests along the design process. This paper describes components to support the development of new maritime technologies by a physical testbed following an open and modular design and show the applicability by testing a shore based bridge.
