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.

Two new locks were introduced in 2009 for training in the new Panama lock conditions with or without tug(s). This video shows the famous "piston effect" when entering the lock at an impressive speed of 10 knots with a high blockage factor.
Port Revel provides shiphandling training using manned models for maritime pilots, masters and officers: http://www.portrevel.com

It is not often that this blog is used to show bad practice, however in this case some pictures tell a whole story. Ship is compliant by design for rigging a combination. How about the operator(s)?

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...

Kiel Pilots introducing Morild Interaktiv AS Virtual Reality Simulator for next-level manoeuvring training

Version from 1st May 2021: Ships that require the services of a pilot need to ensure that the Pilot Transfer Arrangements (PTA) they provide are in compliance with the requirements prescribed under SOLAS V/23 and IMO Resolution A.1045(27) [as amended by IMO Resolution A.1108(29)].

"An old experienced pilot sometimes loses a ship by his assurance and over confidence of his knowledge, as effectually as a young pilot does by his ignorance and want of experience."
Let us remind ourselves every day of the principles of safe seamanship...
