How does GPS work?

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.

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

Today, we embark on a voyage into the intricate world of ship types. From massive container ships to nimble oil tankers, we'll explore the unique challenges each vessel presents.

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

'Shallow Water Effects' - The New KARCO video which promises to bring immense training value for navigators, has been developed using very effective 3D Animation &VFX.

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.

Have you ever wanted to watch a marine pilot in action? Last night, TasPorts was delighted to offer up for auction a pilot boat experience to support Cancer Council Tasmania's 25th Anniversary Gala in Launceston. A second experience will be offered at the Cancer Council Tasmania Gala in Hobart next month. Both events raise funds to support Tasmanians dealing with cancer through advocacy, prevention, support and research. This video was filmed in 2018 (pre-COVID), was broadcast at last...
