Ballistic correction technology could significantly improve the performances of existing weapon systems at a lower cost. An application study of the MEMS based integrated navigation system in the bal- listic correction technology was performed. The speed/position combination model was established in the integrated navigation system. A Kalman filter was used in the integrated navigation system to carry out its optimal estimation, and simulation analysis of the pure inertial navigation system and integrated naviga- tion system were completed respectively. Sports car test of the integrated navigation system was also com- pleted. Results of the simulation and sports car test showed that the integrated navigation system can provide a high quality position and speed as well as accurate measuring information for trajectory correction and control devices, so as to improve the firing accuracy. Therefore, this research has a certain engineering reference value.
