    Abstract

    The launch and impact points of a flight trajectory are estimated using UD Kalman filter and R-T-S smoother. Algorithms are implemented in PC MATLAB and validated using simulated data. The filter performance is evaluated in terms of state error, innovation sequence and autocorrelation of residuals along with their13; theoretical bounds. The R-T-S smoother was found to generate more accurate13; state estimates, which led to better launch point estimation. Launch and impact13; point prediction from real data of a guided target in ballistic mode is also evaluated.
