Open the CIPO recordAbstract From the Canadian patent
A gyrocompassing system intended for land based equipment requiring north reference information includes a novel gyrocompass implementation which enables utilization of high grads inertial sensors while achieving the desired goal of moderate cost. The north finding system is designed to provide high accuracy with fast reaction time over a wide temperature a range without the aid of heaters and other auxilliary equipment. The arrangement is specifically configured to tolerate settling and/or oscillatory base motion without additional reaction time or degradation of gyrocompassing accuracy.

Why it's free to use
- Filed February 27, 1990 and granted December 17, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 27, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 27, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
