OSI TDNS Included in GOTLAND Upgrade

High Performance Submerged Navigation Capabilities

OSI Maritime Systems announced on 5 June that its Tactical Dived Navigation System (TDNS) has been incorporated as part of the first-in-class GOTLAND submarine upgrade for the Royal Swedish Navy. Led by Saab Kockums, the comprehensive modernisation programme for the A19 submarines now includes TDNS with ECPINS Submarine 6.2, chosen for superior submerged navigation capabilities.

In the complex subsurface navigation environment, the requirement to navigate without the aid of external sensors is paramount. High tempo tactical situations require that submarines minimise their above-water signature, which restricts the use of sensors such as GPS. The innovative ECPINS dived navigation methodology offers submarines a unique GNSS-denied capability. Using an advanced algorithm, reliance on sensors is minimised, the submarine can remain undetectable for longer and retains her full tactical advantage.

The confines of the submarine space present a challenging operating environment. OSI worked closely with the Royal Swedish Navy to refine and extend the system’s capabilities and functionality.  To improve operator response and awareness, sensor identification combined with mast management was paramount. TDNS features a bespoke submarine information display providing the operator with quick, easy-to-reference navigation details, improving dived navigation and safety.   

Independently certified to NATO WECDIS STANAG 4564, and the only truly third-party certified naval navigation solution, ECPINS is deployed with the navies of Sweden, the UK, Australia, Brazil, Canada, the Netherlands, Portugal, South Africa, Sweden and the United Kingdom.
