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 term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

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.

"A performance assessment tool for maritime pilotage operations" - by Jørgen Ernstsen, Norway
When the ship is approaching or leaving a port, a local navigational expert, the pilot, is often provided for assisting the bridge team to safely and efficiently navigate the littoral waters.

Opening the building to unveil the Pilotboat "Columbia". Preparing for launchday.

This is Paddy Rooney, Coxswain of the Carlingford Pilot Boat, on the lough which separates County Down and County Louth. The boat operates out of a small jetty at Greencastle - so called after it's Norman castle near the shore and not far from the town of Rostrevor with it's beautiful park and colourful streets. In this film Paddy and his crew rendezvoused with a cargo ship at Greenore Port - which is also a uniquely preserved 1800's railway village .
