In this article an integrated system for dynamic under keel clearance (UKC) assessment is presented. The system was created to improved navigation safety and economic effectiveness in Polish ports. In this paper principle of model operations and utilization with modern, available mobile devices in integration with wireless data transmission technology was introduce

Using laser rangefinders or other distance measuring tools offers an opportunity to create new ship waterplane position finding algorithms in restricted areas. The achieved by such system redundancy of positioning system will affect on ship’s safety and influence navigation which is dominated by one system (GPS and its derivatives). This paper is focused on developed optimization gradient algorithm and its improvement, algorithm with random start position

Maritime surveillance from space is useful for many applications, such as fisheries control, maritime border control and maritime security. A new generation of satellite-borne Synthetic Aperture Radars is able to provide resolutions of down to 1 meter. In the case of maritime targets, however, their motions lead to blurring in the SAR images, so these high resolutions cannot be attained. Scientific research into how to surmount the existing limits on the use of high-resolution images for maritime surveillance would be of great utility. In this context, high resolution SAR data were collected from ships that have been fitted with motion sensors in order to understand vessel motion impact on detection and recognition capability
