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.

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

Blog: https://www.merrimacins.com/understanding-and-preventing-tug-barge-risks/ Understanding and Preventing Tug & Barge Risks The maritime industry relies on tugboats and barges for a wide range of applications. Tugs are used to pilot vessels into and out of ports, while barges are used to transport bulk materials. The relationship between tugs and barges is critical, as most barges are not self-propelled and must rely on the skilled operation of a tug or tugs for propulsion. At Merrimac...

Who knows the S-100 / S-102 electronic card standard? An introduction by the Maritime Simulation and Resource Centre, Canada

The sun was out and was a beautiful day, I was searching for a light house in the area and there was one in Cameron, La. I started my way to the light house not thinking how bad Cameron was hard hit by two hurricanes. After a few dozen downed power poles I was met with the National Guard and the Po Po. Needless to say I turned around and I had passed the port so I decided to drone this area. Not a bad place and a ship was being assisted by two pilot boats. I never tire with maritime...

We are satisfied with the result, and it shows that continued constructive dialogue with the employer pays off," writes Jens M. Sørensen, chairman of Lederne Søfart, in a press release.
