Abstract:	The objective of the project ARIADNA is the design and development of a new concept based on volumetric navigation underpinned by the accuracy of GNSS technologies. The innovative ARIADNA solution encompasses a new series of maritime navigation support systems in order to allow optimization of the infrastructures, the navigation during dense traffic in ports, rivers, channels, lock and their access areas; developing a system which leads to efficient and environmentally-friendly maritime and inland operations. The ARIADNA technology is based on the Volumetric Navigation System (VNS) concept. VNS combines navigation, volume and time information of the craft involved in a specific scenario in order to know the surrounding space occupation or availability to define their relative movements, defining a safety volume around the craft. The knowledge of the safety volume associated to every craft increases traffic efficiency and safety in navigation. In the maritime navigation, the volume" of a ship has been defined as the envelope of the ship after a certain time, taking into account his current speed. The volume takes also into account the extreme maneuvering positions at the given speed with the appropriated corrections for drift due to wind and ocean currents. The Volumetric Navigation concept is integrated into the development of a collaborative navigation tool sharing position, attitude, and volume. The position is accurately provided by GNSS technologies (GPS, EGNOS, etc). Specific GNSS performances in terms of accuracy and integrity are crucial to accomplish a safety navigation tool. So far the use and processing of GPS, EGNOS signals and messages provide the required position and navigation performances, parameters required by ARIADNA solution. In order to develop a collaborative frame and system, it is required to integrate GNSS position and velocity information heading with information provided by AIS (Automatic Identification System) and ECDIS (Electronic Chart Display and Information System). Both technologies are the core technical elements for the ARIADNA system in terms of positioning. Near commercial future activities are related with the system implementation providing warning and maneuvering support for collision avoidance and grounding whilst facilitates risk and warning assessment to vessel and navigation control systems in the infrastructures such as channels, port access areas, narrow inland waterways and congested access areas. ARIADNA future developments are considering different technical and human factors, assessing its integration with maritime existing systems and current maritime regulations, bringing in a valuable tool to avoid human error in navigation, support personal training and enhance best human practices. The paper will present the ARIADNA system architecture focusing mainly on the Volumetric Safety envelope and provide the benefits regarding safety and efficiency improvement in maritime and inland navigation.
