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.

The video was found on some social media channels in June 2020. When so many elementary mistakes are made and so many risks are taken, this is exactly what can happen! It's a demonstrative example of an unprofessional action: 1) Where is the life jacket? 2) No backpack on the shoulders. Use a rope to have the backpack lifted by the deck crew. 3) Where is the rest of the crew (on vessel / on the small boat) for safe assistance? What other mistakes have you discovered? We do not put videos...

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!

The latest summary from PTR Holland on the subject of pilot ladders. Here is the most important information on maintenance, use and replacement & insepection record book.

This study presents a novel decision support process for a pilot dispatching problem in the St. Lawrence River. It integrates a comprehensive set of time-based performance measures, including working time, waiting time, and skill level differences, to optimize fairness and operational efficiency in pilot dispatching.

This cabinview video shows how to control a STS crane, there will follow a video were I show you all the buttons and joystick controls. Lot of people request these video's. This shows how to operate en ship to shore crane with a joystick camera! (DUAL CAM) Make sure you LIKE and SHARE this video is you want more video's like this! Hope you enjoy!

Eerie fog envelops the Disney Wonder as the cruise ship enters the mouth of the Mississippi River from the Gulf of Mexico. A pilot boat approaches to drop off the Mississippi River boat pilot.
The eerie fog made it look like the ship somehow transported to the Pirates of the Caribbean ride.
No sign of Captain Jack Sparrow, but he has to be hiding somewhere. Maybe he's at the Crown & Fin Pub having a tot of Navy Strength Pusser's Rum.

The Good Practice Guide for Pilots 2021 describes the knowledge and skills (technical and non-technical) that the NZMPA believe all pilots should aim to achieve and maintain. It is written primarily for pilots for their own guidance and professional development, but can be used as a framework for pilot training, proficiency and assessment. It is referenced to NZ Maritime Law and Codes.
