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.

This article was published some time ago but is still up to date: The study focuses on maritime pilotage in seven European countries and analyzes the level of job satisfaction and its predictors.

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 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.

This video shows an introduction on the Pull-out Test-Manoeuvre and describes the procedure how to steer through this simple manoeuvre: Turning circle and then put the rudder amidships. The final rate of turn allows to identify stable and unstable conditions.

The Federal New York and the M.S. Westcott Sliding through the Detroit River in May 2026, the Federal New York towered over the tiny but legendary M.S. Westcott, a perfect Great Lakes contrast of scale and tradition. Built in 2024 for Fednav, Canada’s largest dry-bulk shipping company, the Federal New York stretches nearly 656 feet long, carries roughly 34,700 deadweight tons, and was designed specifically for efficient St. Lawrence Seaway and Great Lakes service. Alongside her, the M.S....
