Efficient. Simplistic. Evolutionary.

A trusted and reliable partner for all your navigational requirements is Poseidon Navigation Services. The company opened doors in 2014 and is owned and run by Thomas Gunn, an industry leader with over 40 years’ maritime experience.

While evolving with the demands of the navigation world, PNS Ltd can offer a variety of digital solutions starting with our very own Challenger software which provides weekly updates, voyage planning tools and instant licensing, ChallengerShield for cyber security on the Bridge, ADMIRALTY Digital Publications (ADP), ADMIRALTY Electronic Nautical Publications (AENP), ADMIRALTY Vector Chart Service (AVCS), Witherby Connect & IMO digital titles… the list goes on.  

As well as migrating with the times we believe that tradition should continue to be supported where customers still rely on good old-fashioned paper charts and publications. Providing bespoke services to our clients sets us apart from the rest.
