| Abstract: | Inertial navigation system is used for the military and civilian navigation more and more widely,in which one of the core issues is to improve navigation accuracy. Based on the inertial navigation system data in the characteristics of noise analysis, this paper makes use of the filtering method of wavelet-transform,And makes use of MATLAB simulation tools. The result shows that the method could be used for denoising and improving navigation accuracy , which is practicability and agility to meeting the needs of real-time. |
