How GPS works? Trilateration explained

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.

After a thorough review, the GDWS has officially approved the Morild Ship&Bridge simulator for pilot training according to the German Pilot Training Decree (SeeLAuFV).

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!

In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...

Vos Pace is a Dutch registered ship being seen out by Puffin Pilot vessel at Great Yarmouth 8th June 2021. Vos Pace is 83m long and 18m wide and made in 2015. Puffin is as long as Vos Pace is wide at 18m and 4m wide itself
I run over and managed to grab some nove shots even though the sun was facing into camera some of the time. As Puffin came back it looked even better I thought.
Music by me.

MAN Engines is equipping nine pilot boats from the shipyard Goodchild Marine Services Ltd. in Norfolk, Great Britain, with in-line six-cylinder engines. This is the engine manufacturer's first entry into the British pilot boat segment.
