Title    Design of inpidual guided rocket navigation method
Abstract
With the continuous development of science and technology, inpidual guidance rocket will play a greater role in the future battle field, and has gradually become an important inpidual weapon. As the “eyes” of inpidual guided rocket, navigation system plays a vital role to improve the accuracy. Inertial navigation is a kind of navigation method, it has the advantages of simple equipment, low cost, etc., and it is meaningful. 源`自*六)维[论*文'网www.lwfree.cn
This paper firstly introduces the current situation of the development of the inpidual guidance technology, the application status of pure inertial navigation method in inpidual guided weapon of the study shows. And establish the rocket trajectory model, inertial navigation algorithm model is established in the launch system, and then use quaternion for attitude solution, then solving speed and position of the navigation data. In order to test the accuracy of the navigation algorithm, the navigation algorithm simulation is carried out, and the accuracy of the model is proved by comparing with the real ballistic data.
