Precision analysis is an important task of the exoatmospheric endgame guidance. The conventional method Monte Carlo is time-consuming. Covariance analysis description equation technique (CADET) needs to linearize the nonlinear model, which is complicated and the precision is difficult to be guaranteed. In order to overcome these problems, a new method based on the Unscented Transformation (UT) for nonlinear endgame guidance error analysis is proposed. The error transformation model and the error propagation model are deduced for the nonlinear exoatmospheric endgame guidance system. And they are testified by simulation. Simulation results are compared with that of Monte Carlo method and indicate that the guidance high precision can be guaranteed by the proposed method high at low time-cost and the process is simple.
