In this paper, a new integrity risk evaluation method is developed and tested for laser and radar-based navigation algorithms using feature extraction (FE) and data association (DA). This work is intended for safety-critical autonomous vehicle navigation. FE and DA are two pre-estimator measurement processing steps that aim at repeatedly and consistently identifying landmarks in the environment. A...
With the development of shipping industry, the large vessel safety of sailing in channel becomes one of the most important issues of concern. This paper considers the influences of drift by wind and current, ship's drift distance combines normal distribution, analyzing the probability distribution of ship, and predicting the risk of ship navigation. It provides some reference for the ship's officer...
Currently, various water depth interpolation methods used to construct nonnavigable shallow areas are simply and indiscriminatingly used without taking their respective adaptabilities into consideration. Firstly, three typical methods used to estimate a water depth at an arbitrary position on a chart are summarized as follows: (1) estimating the depth with the shallowest depth of the three vertexes...
The safety of navigation of ro-ro passenger ships has been perplexing the shipping circles, while the problem of vehicle safe stowing and securing is an important factor that affects the safe transportation of ro-ro passenger ships. Some specifications are put forward in home and abroad on the research of safe stowing and securing of vehicle on board ro-ro passenger ships. However, it is lacking in...
AIS (automatic identification system), a new type of marine equipment, together with radar, are all the key navaid for a ship to navigate. Now in the seafaring, it is one of the most attentive research issues how to adequately and effectively use their information to improve the sail safety. The paper developed the integrated target information system based on ECDIS (electronic chart display and information...
AIS (Automatic Identification System), a new type of radio navaid system at sea, has more and more been used on a ship to identify a target and improve the navigation safety at sea. AIS network has also been constructed at the main harbor in many countries to enhance the traffic safety and the management at the harbor. In the paper, AIS system was briefly described. It was studied on AIS network frame...
In safety-critical applications, the set of possible faults have to be divided into two groupes : the first groupe represents the subset of faults which lead to a system failure and the second one - the subset of faults which do not lead (at least immediately) to a failure. The detection/exclusion of a fault from the second group is considered as a false alarm. The problem of GNSS integrity monitoring...
