Article GPS (Part 1) - Structure, mode of operation, technical and physical fundamentals of GPS

by Capt. Gunter Schütze, Thailand/Germany - published

Of course, as a Nautical Specialist, I also deal with the international discussion on the advantages and disadvantages of satellite-based navigation, e-navigation and conventional terrestrial and astronomical navigation.

Article GPS (Part 2), physical and technical errors of GNSS - an error analysis

by Capt. Gunter Schütze, Thailand/Germany - published

In my announced sequel, the second part of GPS, it is primarily about the technical and physical operational and functional limitations to which GPS is subject. These limitations, in part, have serious implications for the accuracy of GPS, and even go as far as limiting the functionality of GPS in its functions or even making it impossible. In doing so,

The vulnerability of GNSS in shore-based use is definitely different and to be regarded as much more risky than on the high seas.

Video Presentation of manned ship models at Port Revel Shiphandling Training Centre

Port Revel is used for shiphandling training of maritime pilots, masters and officers on a 5 ha lake with 11 manned model ships representing 20 vessels, and 4 tugs at scale 1:25 and DGPS tracking system. Instructors are former maritime pilots.
Training on the scale models provides experience that could never be gained on real ships for the simple reason that neither ship-owners nor local authorities would allow such risks to be taken. Scale models allow the shiphandler to make mistakes. Scale models allow experimentation on ship behaviour to explore unknown fields beyond the limits of safety.
Periodic training on scale models will maintain your shiphandling skills at the highest level and periodic evaluations will show it.

Specialized training for maritime pilots

Quebec City, Quebec, Canada – June 23, 2020 – The Maritime Simulation and Resource Centre (MSRC), a world-class pilot simulation training and port feasibility studies facility, is pleased to announce the release of an informational video on the new S-102 standards on surface bathymetry products.

In the video, Captain Pascal Rhéaume, pilot and member of the technical committee for the Corporation of Lower St-Lawrence Pilots, an active stakeholder involved in the project, introduces the progress made on the development of the S-102 standards. He presents a brief history of navigational charts and explains how technology has allowed these charts to evolve concurrently with the maritime industry as a whole. Captain Rhéaume highlights the groundbreaking benefits of these new standards and how they can greatly improve navigational safety for all seafarers across the globe.

As mentioned in a previous joint press release on November 5, 2019, the Canadian Hydrographic Service (CHS) wishes to promote the implementation of the new S-100 standards to provide mariners with access to additional information (bathymetry, surface currents and water levels) and greater versatility in the display of these data. CHS took advantage of World Hydrography Day to present the work conducted in relation to the S-102 standards and to broadcast Captain Rhéaume’s video.

Article German pilots establish the "Pilot Information Assistant - PIA" project

by Ship&Offshore DVV Media Group - published

The PIA project of German pilots is a great maritime success story and ensures greater safety and efficiency on German shipping routes. Thus, with no exceptions, all of the approx. 890 German maritime and port traffic controllers could be gathered for use of the PIA system and its PPU.
