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,

At first glance, the glide of these orange powerboats up and down Belfast Lough seems an almost effortless task, but close up this is a very skilled trade and constant management of risk 24/7 in high and low seas, jumping from ship to boat to land taking safe control of the great volume of steel vessel coming in and out of this busy port. Though a hub of...
