RCN submarines to receive new tactical navigation system

OSI Maritime Systems is to provide its Tactical Dived Navigation System (TDNS) to the Royal Canadian Navy (RCN) as part of a fleet-wide submarine upgrade programme.

TDNS is fully qualified to military specifications, OSI announced on 6 August. The system for the RCN will include a Digital Maritime Operations Plot (D-MOP) flatscreen display and ECPINS Submarine.

‘Combined, the two solutions provide a state-of-the-art tactical navigation advantage,’ OSI claimed.

D-MOP hardware and system architecture is custom-fitted to enhance crew navigational and tactical efficiencies, it added, while ECPINS Submarine exploits technology by offering features that increase the subsurface performance by being able to operate with or without the aid of sensors.

In common with other OSI solutions, deployed on submarines operated by nine navies, TDNS complies with the NATO STANAG 4564 standard for warship electonic chart display information systems.

The four submarines in the RCN fleet (HMCS Victoria, HMCS Windsor, HMCS Chicoutimi and HMCS Corner Brook) have struggled for operational availability for some years. They were dry-docked in 2019 for long-term upgrades  to ensure they remain operational until the late 2020s.
