Determination of start and end points of a flight trajectory using UD filter and R-T-S smoother 13;

The start and end points of a flight trajectory are predicted using UD Kalman filter and R-T-S smoother. Algorithms are implemented in PC MATLAB and validated using simulated data. The R-T-S smoother was found to generate more accurate state estimates, which led to better start point prediction. Start and end point prediction from real data of a guided target in ballistic mode is also evaluated.
