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.

Port operations, whether these are being performed on water or on land, are often not without risk. Pilots boarding a ship while sailing, navigating through narrow passages, collision avoidance with other smaller or larger vessels, discharging and moving cargo on land, walking between container handling equipment and trucks…

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.

Theory on Wind drift will be shown together with demos using SAMMON planning on the effect of thrusters to have some effect on drift speed & direction

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

As a part of the ISTLAB project the impact of external factors on pilots’ activities in a remote pilotage situation has been examined in Rauma.

CMA CGM Columbia container ship arriving from Shekou port, and transiting thru Hong Kong, destination Singapore
a rare capture of TWO harbour pilots boats to carry two pilots leaving off the container ship
Columbia is only a 300m long 48m wide vessel, only 9200 TEU capacity but it has separate bridge tower and chimney. The ship was built in 2015.
