【Abstract】 The key technology of real-time fusion & selecting and differential smoothing stationary speed based on the rocket’s measurement data is studied. Aiming at the traits of more sources information of vehicle,the mathematical model of fusion & selecting for two or more sources measurement data of the rocket is established,and the time-fusion method to solve the differential smoothing stationary speed leaping is given. The data lapse error before the fusion & selecting is eliminated in effect,and the problem that the fusion and selecting reliability is debased because of the source data lapse error is solved. The precision of the cross fusion of the measurement information is improved. The application effect of this method is very good.更多还原
