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.

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.

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 article describes the findings from two studies that utilised an integrated systems thinking framework to understand how pilots make decisions and what factors are perceived to influence their decisions.

Join Great Lakes maritime historian and antiquarian Brendon Baillod as he discusses the restoration and conservation of a rare and very early 1865 Thompson's Great Lakes Coast Pilot. Early coast pilot books were kept on every schooner and steamer and Lakes and contain important details about the history of harbors, navigation, obstructions and shipwrecks on the Lakes. This 1865 Thompson's is among the rarest and also badly in need of stabilization. Enjoy this two part series where this...

A portrait honouring the "vital role" women play in the maritime industry has been unveiled.

A cargo ship lost power while approaching the dock at the Port of Tampa Thursday. Officials said quick thinking by harbor pilots and tug boats got it under control.
