Submarines operate in one of the most challenging environments on the planet. Quantic Thistle has designed and manufactured encoders that measure the angular position of electric auxiliary drive motors as well as linear transducers for use reporting the precise position of the control surfaces (hydroplanes and rudderons) that steer the boat.

The Royal Navy’s Astute Class hunter killer submarines all utilise encoders designed by us, as will the new Dreadnought class ballistic missile submarine fleet.
