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.

Briese research are extending their cooperation with Nautitec for their research training projects. As from immediate effect, a model of the research vessel “Maria S. Merian” can be used for tailor made training at NAUTITEC´s Leer-based simulator facilities.

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

Importance of Wearing Safety Helmets at Work. ... Hard hats or Safety helmets act as the first line of defense against head injury, but they only work when they are worn correctly. Thus, it's safe to say safety Helmets save lives and reduce the risk of brain injury. #wearenavigators info@wearenavigators.com www.wearenavigators.com

This video explores the question of why ships are so difficult to manoeuvre in reverse.

Over the past few years a number of pilot transfer accidents have occurred resulting from total failure of the side ropes, one school of thought is that the methods of securing a pilot ladder is a factor in such occurrences.

Luke Sorensen began his career as a Marine Pilot in 2011. Now the Manager of Pilotage Services, North Queensland Bulk Ports (NQBP), he mentors Pilots moving through the NQBP Training Framework to become competent and confident in bringing ships into berth at our ports. Luke explains the process of mentoring.

In our new new section “Five questions for ..." Marine-Pilots.com introduces pilots and other market players to our readers in short interviews.

Today we have talked to Porthos Lima, Rio de Janeiro Pilots Operations Director.
