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.

The Master and pilot are dependant on each other for a safe and successful beginning or end of a voyage. They are both operating in a foreign environment.

A portable pilot unit (PPU) is a portable navigation aid system designed specifically for ship pilots, such as the SIRIUS series from TRENZ in Germany (www.trenz-ppu.com).

Electronic warfare in the Baltic Sea is escalating rapidly, with GPS and AIS disruptions posing growing risks to maritime navigation. Russia’s hybrid strategy is targeting both safety and stability in one of Europe’s most critical shipping regions. Pilots and crews now face a new reality: navigating under threat.

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.

As praticagens que atuam no litoral atingido pelo ciclone extratropical estão em estágio de alerta, avaliando constantemente os efeitos da ressaca e as condições de segurança dos canais de acesso. O objetivo é evitar acidentes e minimizar os impactos na logística e operacionalidade dos portos.
Em São Francisco do Sul (SC), o gerenciamento da situação já ultrapassa 12 horas, monitorando lanchas, navios fundeados e enviando rebocadores para o cais. Em Itajaí (SC), a preocupação inicial...

Soon a Vega will launch from Kourou carrying a payload of several satellites. These will be delivered into orbit by a new multi-payload system developed by ESA. Among these small satellites, E-SAIL. This microsatellite is dedicated to supporting maritime traffic and making seafaring safer. It is part of ESA’s SAT-AIS programme, which aims is to increase the coverage of the Automatic Identification System for ships. This system is a short-range coastal tracking system currently used on...
