ABSTRACT:
A computer-implemented method for estimating track error covariance of a sensor track data in a Link 16 tactical data link network from track quality involves receiving at a computer system the sensor track data on a ballistic target including the track quality and by estimating the track maturity, the position and velocity error covariance eigenvalues (λp, λv), and the position and velocity error covariances (Cp, Cv), the track error covariance of the sensor track data is calculated. The resulting error covariance is provided to the weapons control systems for more accurate engagement of the ballistic targets.
