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.

Managing the Attributes of Pilot Errors in the Process of Redevelopment of Marine Pilot Reliability Index MPRI): A Systematic Literature Review

The ICS Guide to Helicopter/Ship Operations is the industry standard best practice guide for shipping companies, ships’ crew and helicopter operators.

New guidance for PBAs with trapdoors. Released 4.11.2020 at NZMPA Conference in Dunedin, NZ. Distinct difference to suggestions in many other countries, is that we challenge operators who have the ladder suspended from the accommodation ladder (gangway) and not secured to the ship. SOLAS states that pilot ladder shall be secured to the ship, and securing strongpoints, shackles and ropes shall be as strong as the sideropes.

From "Casual Navigation": In this video, we investigate the Pilot Ladder. It is a crucial piece of equipment, used for embarking and disembarking a harbor pilot at sea.(contains advertising)

It has been shown that a majority (51%) of pilot ladders is secured by means of D-shackles, when secured at intermediate length. Previous research (Evans, 2020) has proven that this method has only about 50% of the strength of the pilot ladder when secured at full length (“double ended ladder”), or by means of the “endless-sling” method.

A new generation Pilot Boat ! - One of the first IPS propelled workboat - A service speed of 30 knots - A lightweight and solid construction in aluminium - Fast crew operations and low running costs The specifications of this boat have been carefully studied to optimise performance and reliability, while minimising running costs, especially fuel consumption. Both light and powerful, this new 12-metre craft is capable of rapid turnarounds at a service speed of 30 knots. More information on...
