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 Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

Bremen, 24.10.14: How to navigate a ship properly? How do you enter which port? Future captains, but also experienced pilots train in the "Ship Handling Simulator" at Bremen University of Applied Sciences.

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

This video explains the impact of lateral resistance on the turning circle of a vessel using animations. The video explains the term lateral resistance, shows an example of its impact on the turning circle and its associated aspects (advance, transfer, tactical diameter and drift angle).
Contents of this video will benefit mariners preparing for exams (written and oral examinations).

"A performance assessment tool for maritime pilotage operations" - by Jørgen Ernstsen, Norway
When the ship is approaching or leaving a port, a local navigational expert, the pilot, is often provided for assisting the bridge team to safely and efficiently navigate the littoral waters.

A collection of action from the St Johns Bar Pilot Association In the early 1800′s as the commercial ports along the St Johns River began to develop, a select group of brave and skilled seafarers would row to sea to meet arriving cargo sailing ships. These daring individuals would use their extensive local knowledge to safely guide the sailing ships across the treacherous sand bars that guarded the river entrance. This was the origin of the St. Johns Bar Pilots. Initially it was a bit of a...

At Safehaven Marine it was great to be able to launch a new pilot boat for the Port of San Ciprian in Spain after nearly 2 months of Lockdown. She was nearly finished at the start of the lockdown. It sure was nice to be on the water again, even with social distancing.
We wanted to do something nice to lift everyone's spirits during these challenging times around the World, so we did a fly past our home Port of Cobh in Thunder Child II (Safehaven’s Transatlantic record attempt vessel) in...
