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.

Version from 1st May 2021: Ships that require the services of a pilot need to ensure that the Pilot Transfer Arrangements (PTA) they provide are in compliance with the requirements prescribed under SOLAS V/23 and IMO Resolution A.1045(27) [as amended by IMO Resolution A.1108(29)].

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 technology group Wärtsilä will supply a complete navigational simulator upgrade for the Le Havre pilot station in France. The intention is to provide the pilot station with a totally new simulator specifically adapted to the requirements of the pilots’ operations. The order with Wärtsilä was placed in February 2020.The new unique visualisation system to be supplied is based on 14 DP projectors, comprising seven main circular and seven ground projection systems. It features a panoramic 350-degree screen.

Many people wonder how ships made it across entire oceans without getting lost in the seventeenth century. Aaron introduces seventeenth century navigation to us today by beginning with piloting.

The busy Strait of Messina which separates the island of Sicily from the Italian mainland is now home to a new pilot boat, manufactured by Bellcraft and powered by Volvo Penta’s Inboard Performance System (IPS).

ADNOC Logistics and Services (ADNOC L&S), the shipping and maritime logistics subsidiary of the Abu Dhabi National Oil Company (ADNOC), announced today that it has signed a new 25-year agreement to provide critical marine services across all Petroleum Ports in Abu Dhabi on behalf of the Petroleum Ports Authority (PPA). This includes the onshore Jebel Dhanna Ruwais Petroleum Port and the offshore Das Island, Zirku Island and Mubarraz Petroleum Ports in the Emirate of Abu Dhabi.
