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 webinar, Rev. David Reid, AFNI looks at why we need to learn this skill and put it to work to promote safety at sea and the wellbeing of our colleagues. Are we mind full or mindful?

What happens when GNSS fails? In maritime navigation, this isn’t a hypothetical scenario – it’s a growing risk. Spoofing, jamming, and GNSS outages are increasing, especially in the Baltic Sea region. A failure can cripple navigation systems – with potentially serious consequences.

The purpose of this quantitative, ex post facto study was to assess P-J fit theory by examining the relationship between personality traits, as measured by Jackson’s (1984) PRF-E, and selection for a maritime pilot job.

A maritime pilot tells us about why he loves switching ships in midstream.

In this eye-opening episode of Sea Views, host Julia Gosling speaks with Captain Andrew Moll (Chief Inspector, UK Marine Accident Investigation Branch), Ari Palmers (Senior Maritime Pilot, Netherlands), and Adam Parnell (Director, CHIRP Maritime) to confront the serious dangers faced by maritime pilots — especially during pilot transfers, where fatality rates remain alarmingly high.
