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.

OHB Digital Solutions GmbH develops systems for monitoring the GNSS frequency bands as well as detection, classification and localization of intentional or unintentional interference sources. Many stakeholders and applications as well as critical infrastructure providers are relying on GNSS to provide their services. Since Global Navigation Satellite Systems (GNSS) are widely used in safety and value critical applications, GIDAS detects, classifies and localizes any GNSS interference...

Pilot transfer arrangement is a sensitive topic to be discussed among the pilot’s fraternity. Although ships are designed and operated with compliance to the SOLAS requirements in all respects including the pilot transfer arrangements, there has been numerous deficiencies observed related to pilot transfer arrangements. The small deficiencies from the part of ships cause life threatening accidents for pilots and sometimes to the ship staff themselves. There are many instances of defective ladder and complacency in proper rigging of ladders has been reported almost every day in different parts of the world. Many pilots lost their life, severely injured for life and face many minor to major accidents. The latest incident being the Capt. Timothy Murray of Sandy hooks Pilot.

Stanchions therefore are an often-overlooked part of a pilot transfer arrangement and therefore I
want to give them more attention in this article. They proved to be the cause of a whole series of accidents, some of which were even fatal.

Based in Estonia, Baltic Workboats is a long-tenured boatbuilder for multiple markets, including the demanding pilot boat sector. Late in 2025 in New Orleans BWB debuted a new hybrid electric 17m model, a boat that leans on more than 15 years of accrued experience building larger hybrid electric vessels. Carl Mahler, BWB’s North American sales lead and a harbor pilot himself, discussed with Maritime Reporter TV the value proposition offered by the shipyard, from manufacturing process to...

We bid farewell to our Otaru marine pilot just outside Otaru Harbor, Japan. The crew of the pilot tug were particularly fastidious about not marking up the side of the Viking Orion during the operations, spraying the interface with water, even though that might have made the transfer more hazardous for the pilot.
