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.

A portable pilot unit (PPU) is a portable navigation aid system designed specifically for ship pilots, such as the SIRIUS series from TRENZ in Germany (www.trenz-ppu.com).

This paper aims to explore the possibilities of improving team performance on the bridge in pilotage waters. The pilot and the bridge team have a common goal: to navigate the ship safely and smoothly.

Online survey among maritime pilots in Germany: job-related stress and strain and the effects on their work ability.

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.

What happens when next-generation maritime data is put to the test in some of the most complex navigational environments? This video shares insights from a major international S-100 simulator trial, delivered in collaboration with Carnival Corporation’s CSMART training facility and a wide network of global partners. Together, we explored how S-100 data sets perform in realistic, high-pressure bridge scenarios—particularly in confined waters where precision and timing are critical. Bringing...

Marine pilot boats transfers marine pilots between port facilities and large commercial ships requiring compulsory navigation assistance. The Port Authority of Jamaica manages and regulates pilotage operations across the island's harbours. Essential for ensuring safe maneuvering and docking in coastal waters and busy shipping lanes. 00:00-Marine Pilot Boat in Kingston Harbour 01:59-Marine Pilot Boat in Kingston Harbour 04:26-Outro https://www.facebook.com/people/Naftal-Shipspotting/...
