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 study addresses that gap by examining sustainability thinking not simply as an issue of awareness, but as a problem of training integration in a safety-critical professional context.

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

I’ve wanted to visit the Warsash Maritime School ship-handling centre since before I ever set foot on a ship. It’s visited by pilots from all over the world for the kind of specialist training, realistic simulations and real-world expertise you rarely get elsewhere.
As a Tug Master, I handle ships by pulling and pushing them around, so to see these intricate manoeuvres using only the ships equipment really fascinated me.
I can’t thank all the instructors, Warsash and Solent uni enough for...

The role of a Tug Master undertaking harbour towage activities is a very specific one. He/she has to, alone or in cooperation with other Tug Masters, assist a ship in a safe and efficient way using his/her tug to the best of its qualities. 

Efforts to free the giant container ship are continuing after the 400m-long vessel became stuck in the Suez canal. Local authorities attempted to dislodge the 220,000 ton vessel from the banks of the canal using tug boats, but the megaship remains stuck more than one day after it ran aground.
