Abstract
A trajectory identification method applying parameters measured by GPS is put forward in order to improve the precision of trajectory correction. This method can decrease influence of random measurement error. At the same time, the trajectory inclination angle can be calculated indirectly and the initial parameters can be obtained for trajectory prediction. The precision of the method was calculated by Monte Carlo method. Simulation results showed that the relative circular error probable was 0.09% under the precision of recent commercial GPS receiver that processes signal of single frequency and C/A code, which could satisfy the precision requirement of trajectory correction fuze.
