SPACIDOCourse correction system

SPACIDO (System with Accuracy Improved by Doppler Cinemometer) is

a course correction system in range that operates by comparing the

actual trajectory with the theoretical trajectory.

PRINCIPLE OF OPERATION■

SPECIFICATIONS■

Field artillery accuracy improvement is a matter of continuous effort. Greater accuracy provides better engagement of high pay-off targets, minimises collateral damage effects and the safety distance with respect to friendly troops, while reducing the ammunition consumption.

Less fired rounds allows a shorter time on the firing position, increased survivability, reduced logistics and lower costs.

SSPACIDO, consisting of a muzzle-velocity measuring radar integrated into the gun and a NATO-standard fuze with 2-inch thread, can be used with all in-service or under development 105mm and 155mm ammunition.

SPACIDO generates an improvement of accuracy of a factor going up to 5 at long ranges.
