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.

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...

The technology group Wärtsilä will supply a complete navigational simulator upgrade for the Le Havre pilot station in France. The intention is to provide the pilot station with a totally new simulator specifically adapted to the requirements of the pilots’ operations. The order with Wärtsilä was placed in February 2020.The new unique visualisation system to be supplied is based on 14 DP projectors, comprising seven main circular and seven ground projection systems. It features a panoramic 350-degree screen.

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)?

This safety video examines the safe set-up of pilot ladders and details the safety checks that should be carried out before using a plot ladder to ensure a safe boat transfer.

SOMERSET, Mass. – DATE – The Galveston-Texas City Pilots have ordered a fourth launch from Gladding-Hearn Shipbuilding, Duclos Corporation. Delivery is scheduled for in late 2022.

Editors Note:
Safety is different

"No hard hats, no Hi-Viz clothing (in case pilot falls in) the one at 5:16 has not even got a life jacket - absolute cowboys!"
