Replacement of Gun Movement Tachometers:

On contract with Northrop Grumman, AdaRose's software solution was able to replace aging Analog tachometers that had been experiencing high failure rates in the field. The new Paladin Digital Fire Control System removes the Azimuth and Elevation Tachometers that controlled the rate of gun movement and replaces them with AdaRose's software solution that substitutes digital rate data obtained from the Inertial Measurement Unit. With the rate movement algorithms developed by AdaRose, gun pointing accuracy is now better than that of the legacy system. The worst case error in the legacy system was predominantly in the azimuth plane at high gun tube elevations, sometimes as large as 0.8 mils. The new tachless system implements a systematic error reduction routine to improve this error to less than 0.2 mils on average.
