This, and the following three papers, were first presented at GNSS 2000, the Third European Symposium on Global Navigation Satellite Systems held in Edinburgh, Scotland from 1st to 4th May 2000.This paper presents the methodology and a practical implementation approach to perform GNSS Safety Assessment and Certification with due consideration of the satellite navigation system users. It places Galileo GNSS in a total system that includes vehicles, on-board equipment, crews and traffic controllers and defines the necessary organisation for implementing safety analyses right from the early design phases of navigation systems. Civil aviation has very demanding requirements based on objectives for air navigation safety. It is much better organised on a worldwide basis than other GNSS users and is considered in this paper as the leading study case. Some methods are then proposed to build a bridge between all user organisations and to set up a common approach to certification.

The study is aimed to assess the navigation safety in the port surrounding the area as part of the Indonesian Government�s efforts to increase the port performance and minimize the cost of maritime logistics. The port navigation system and infrastructure such as vessels traffic management system, navigation lanes, port basin, quay, etc. play an important role in determining the productivity and efficiency of the port, especially in the busy port such as Tanjung Priok, Indonesia. Any accident would interrupt port activities and creates unnecessary costs. Formal Safety Assessment method, as introduced by the International Maritime Organization was implemented in the study. The assessment was carried out using qualitative and quantitative risks analyses, based on the available data and information gathered from various sources. It was identified that accidents occurred in the port waterfront were mainly due to the ships, environment, human factors, and management. Results of the assessment were then used as the basis for proposing an improvement strategy.

The concept of ship's domain plays an important role in navigating a ship. It is a criterion of safety in the process of making decisions by the navigator – in analyzing and assessing a navigational situation and in performing the right manoeuvre. This concept is particularly useful in restricted areas, including narrow fairways, which results from the fact that in such waters a manoeuvring area is restricted so that the criterion of the closest point of approach (CPA) cannot be used. This author has analyzed definitions of ship's domain and methods of its determination found in the literature on the subject. Then a method of navigational safety assessment using the fuzzy domain concept is proposed in reference to a ship in a restricted area. The concept and method of determination have been, respectively, defined and described. The method is based on relevant navigators' knowledge. The methods and tools for knowledge acquisition and representation make use of artificial intelligence. Ships and navigational areas of various size have been considered.
