On April 27 2015,  it was announced that Northrop Grumman Corporation's Sperry Marine business unit has been selected to design and supply gyrocompass navigation systems for 12  Kingston-class coastal defence vessels for the Royal Canadian Navy, as a subcontractor to SNC-Lavalin Defence Programs Inc.

The contract will include Dual NAVIGAT X MK1 gyrocompass systems, NAVITWIN IV Heading Management Systems and a complete suite of Heading Repeaters. Installation will start in June 2015 and extend through early 2017. Six of the vessels being upgraded are based in Esquimalt, British Columbia and six are based in Dartmouth, Nova Scotia, where the first field tests will be conducted this summer.

NAVIGAT X MK1 Gyrocompass System

The NAVIGAT X MK 1 Mod 7 marine gyro compass provides highly accurate heading information in extremely heavy seas. The system is equipped with a special gyrosphere container, with a unique centering pin retaining arrangement that is mounted in an additional gimbal system. This allows an almost unlimited freedom of roll and pitch (±90°).

BENEFITS:

* Complies with IMO regulations A.424(IX), A.694(17), A.821(19) - High-Speed Craft (HSC) and ISO 8728
* Comprised of one single unit
* Type-approved rate-of-turn output
* Gyro system remains north stabilized during power interruptions of up to 3 minutes
* Short maintenance and repair times - low service costs.
