Abstract From the Canadian patent
Described herein is a method of controlling the operation of a missile launcher (12) by predicting the landing position (22) of a missile (16) in flight before it lands. The method includes tracking the missile (16) as it travels along its trajectory (18) until it reaches its apogee (20) and calculating the landing position (22) to provide a feedback correction signal to launcher (12) for the next missile to be launched. By utilising a feedback correction signal in this way, the time to hitting a target (10) from the time of engagement is substantially reduced.

Why it's free to use
- Filed September 30, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 30, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 30, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
