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.

This video shows an introduction on the Pull-out Test-Manoeuvre and describes the procedure how to steer through this simple manoeuvre: Turning circle and then put the rudder amidships. The final rate of turn allows to identify stable and unstable conditions.

Another video by Knud Benedict: This movie reveals some practical insight into regions of course stable / unstable conditions under wind. And I dare to say you can get some insight into other stability types and analogies, too!

Ships don't exactly have brakes. Lou Vest, a retired Houston ship channel pilot tells us about a close encounter between a ship and a barge.

London Pilots (PLA) have issued an excellent quick reference guide for Pilot Transfer arrangements, which can be used for pilots as well as ship’s crews. Please take not of this document and if you can, try to incorporate it into your procedures.

To monitor the vessel’s progress, the pilot had set up his portable pilotage unit (PPU). He had connected the rate-of-turn generator to the vessel’s pilot plug and had set a variable range marker on the radar with a radius of 0.5 nm.

Great image video of the Italian pilots (Federazione Italiana Piloti dei Porti).

Safehaven Marine have delivered one our Interceptor 48 pilot vessels to the San Juan Bay Pilots, Puerto Rico.
This marks Safehaven Marines 41st pilot boat delivered to portsWorldwide. ‘Harbor Thunder’ a very striking
design, she is powered by a pair of Cummins QSM11 engines at a heavy duty rating of 450hp, allowing the
vessel an economical continuous operational speed of 22-23kts.
