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.

The ICS Guide to Helicopter/Ship Operations is the industry standard best practice guide for shipping companies, ships’ crew and helicopter operators.

Pilotage is being able to navigate safely into and out of a harbour/anchorage/port knowing where you are at all times, where your hazards are and a safe route in/out. This is particularly useful if you are heading into somewhere new or a challenging/busy area – or both!

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.

Die Lotsenbrüderschaft Elbe ist ein geschlossener Kreis, der sich nicht gern in die Karten schauen lässt. Wer dort Mitglied werden und bis zu 400 Meter lange Containerpötte in den Hamburger Hafen steuern möchte, muss hohe Anforderungen erfüllen. Bewerber müssen mehrere Jahre lang zur See gefahren sein, um ausreichend Fahrpraxis zu haben. Aber es gibt immer weniger deutsche Seeleute, weil die Reeder billigere Kräfte aus dem Ausland bevorzugen. Dadurch wird es zunehmend schwierig,...
