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.

Here’s a cool little video of the 12.5m Barracuda SV we have just launched out on her rough weather sea trials recently, with some great Arial drone footage of her going through some fairly big breaking seas offshore.
Built for ‘Future Defence’ in the USA she is designed for search & rescue and coastal patrol duties. She is fully self-righting, able to recover if capsized by a large breaking sea and capable of all-weather operations. Powered by a pair of Caterpillar C8.7 650hp engines, ZF...
