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.

The Maritime Pilots Institute is the premier training facility for River Pilots employing a mix of virtual and real world facilities. Located in Covington Louisiana, we are 45 minutes from downtown New Orleans while offering the safety and amenities of small town life.
The training presents a balance between simulated locations with a variety of environmental conditions and manned scale models of cargo ships in a series of lakes with docking and currents and live factors such as wind and...

Briese research are extending their cooperation with Nautitec for their research training projects. As from immediate effect, a model of the research vessel “Maria S. Merian” can be used for tailor made training at NAUTITEC´s Leer-based simulator facilities.

A pilot boat is a specialized vessel that is used to transport pilots to and from ships that are entering or leaving port. Pilot boats are typically small, fast vessels that are designed to operate in a variety of weather conditions and sea states.

Over the past few years a number of pilot transfer accidents have occurred resulting from total failure of the side ropes, one school of thought is that the methods of securing a pilot ladder is a factor in such occurrences.

On 6 November 2017, the fully laden, mini cape-size dry bulk carrier Orient Centaur was transiting the South Channel, Weipa, Queensland, outbound under the conduct of harbour pilots as part of a trial introduction of this size of ship to the port. While in the South Channel, the ship’s main engine shut down due to a loss of water from a cracked engine cooling component, and propulsion was lost. Shortly after, the ship grounded on the northern batter of the channel. The stern then slowly...
