How GPS works? Trilateration explained

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 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.

Training video III on the correct behaviour in case of man overboard

The need to hold such a webinar was felt from the interaction over several months of AIMPA members through its President, Capt. Gajanan Karanjikar, with Capt Simon Meyjes and Capt.Ravi Nijjer - both instrumental in the thorough upgrade of pilotage operations Safety management systems in parts of Australia. From these interactions, AIMPA has come to the firm conclusion that a thorough upgrade of maritime pilotage management systems in India is necessary. Holding a webinar would be a good...

This video shows an introduction on the Spiral-Test-Manoeuvre and describes the procedure how to steer through this manoeuvre and measure the data needed. The results will be displayed in a characteristic diagram allowing to identify stable and unstable conditions and related, detailed information, e.g. spiral loop width and height, rudder angle of neutral effect. Samples of stable and unstable ship behaviour demonstrations will be shown by Fast Time Simulation using the SAMMON Planning tool.

Do you ever leave the harbour to get on a vessel you will guide along without a ritual? Whatever we trust in, whatever the rituals or traditions you Marine Pilots have - when you board your pilot boats, climb the ladders, get the vessels through the harbour - keep them and cherish them, they are good and they are important.

Today a look at a special vessel that is commonly seen on the Astoria waterfront: the pilot boat that takes pilots to and from passing ships.
