    Opis:
    The aim of the paper is to analyse the length of time that ships spend in the Port of Gdansk. It is based on the examination of the time when ships come into and leave the port. Source of data used in the study is public web platform - Marine Traffic. Analysis which was conducted, enables to get information about duration of ships servicing in the port with a division into dimension, load capacity and type of the ship. Due to that information, it is possible to observe the duration of complete service for each vessel, including entering the harbour, reloading and the departure. Gained knowledge would allow to forecast, plan and model future development operations more properly. In addition, due to the method based on counting the number of hours that ships spend in the harbour, it is possible to estimate the amount of pollution emitted to the air.

    Opis:
    Modern technical ship systems very often use information and communication technologies. One of the basic requirements of these systems is ensuring time synchronization that aim is to coordinate clocks of all devices working in a computer network. This requirement results from, among others, the necessity to log events with a unified timestamp. To achieve this goal, most frequently expensive time servers are used. This article presents an easy method of time synchronization, which can serve as a reserve or alternative solution to the methods currently used. That is why a proprietary software has been developed, allowing to expand the functionality of a PC so that it can operate as a time server. A time reference in proposed solution would be provided by a GPS receiver. The developed application allows, with the use of the NMEA protocol, to synchronize the current time with the GPS receiver and then, with the help of the SNTP protocol, to distribute it to all network devices operating on the ship.

    Opis:
    LitPOS (Lithuanian Positioning System), the network of continuously operating GNSS (Global Navigation Satellite System) stations, became operational in July 2007. It provides data both for real-time and post-processing applications. LitPOS stations cover the whole territory of Lithuania. There are 31 of LitPOS GNSS stations in total network. Also LitPOS network includes 3 ASGEUPOS (Poland) and 6 LATPOS (Latvia) stations. LitPOS network data processing and analysis of station’s velocities was done using Bernese 5.2, TSview and CATREF programs. Results of analysis show that North/East velocities of the LitPOS stations are very homogeneous what leads to the conclusion that there are no any significant horizontal deformations of Earth’s crust in the territory of Lithuania. Up components of LitPOS stations velocities fit very well to vertical movements of Earth’s crust as described by the land uplift models of Fennoscandia.

    Opis:
    In order to enable port operations, which require an accuracy of about 10cm, the German Aerospace Center (DLR) operates the Maritime Ground Based Augmentation Service (MGBAS) in the Research Port of Rostock. The MGBAS reference station provides GPS dual frequency code + phase correction data, which are continuously transmitted via an ultra-high frequency (UHF) modem. Up to now the validation of the MGBAS was rather limited. Either a second shore based station was used as an artificial user, or measurement campaigns on a vessel with duration of a few hours have been conducted. In order to overcome this, we have installed three separate dual frequency antennas and receivers and a UHF modem on the Stena Line ferry vessel Mecklenburg-Vorpommern which is plying between Rostock and Trelleborg. This paper concentrates on the analysis of the highly accurate phase based positioning with a Real Time Kinematic (RTK) algorithm, using correction data received by the UHF modem onboard the vessel. We analyzed the availability and accuracy of RTK fix solutions for several days, whenever the ferry vessel was inside the service area of the MGBAS.
