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.

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.

In this webinar, Rev. David Reid, AFNI looks at why we need to learn this skill and put it to work to promote safety at sea and the wellbeing of our colleagues. Are we mind full or mindful?

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....
