How does GPS work?

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.

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!

Tom Mellor - C​hairman of the IHO Electronic Navigational Chart Working Group (ENC WG) and Head of Digital Standards at the UKHO - explains what the IHO's ECDIS and ENC Standards mean.

Maneuvering ships are complex operations with high-risk involved. Just like nautical projects, they need to be simulated on training centers before approved. In a scenario of growing ships and limited waterways, state-of-the-art technology is essential to safely increase ports efficiency. That is why Brazilian Pilotage brought the most modern bridge simulator next to the maritime regulatory entities. Located a few minutes from government agencies, in the brazilian capital, our training...

Safehaven are very pleased to have signed contracts with the Northeast Marine Pilots, Newport Rhode Island in the USA for one of our Interceptor 48 Pilot boats

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...
