Research on Integrated Navigation Technology based on the dynamic, static filtering algorithm Shi jianjun 1, Qiu lei 2, Wang xiaodan 2, Xue xudong 2, Hou junnan 2 China Xi'an Satellite Control Center, Xi’ an, China 1. s971232155@ Abstract: This paper use d the dynamic, static filtering algorithm to integrat e GPS, Beidou navigation system and inertial navigation and provides a safe and bined navigation system. The system design ed of dynamic filter to get d ynamic filtering result by integrat ing the GPS and d ynamics model of inertial navigation system us ing Kalman filtering principle . Then the system got the final state vector sequence by integrat ing d ynamic filtering result and t he Beidou navigation system using t he sequential adjustment principle . The result about n umerical simulation of integrated navigation system show that on the one hand bination can solve the poor dynamic performance and poor anti-interference ability problem of single satellite navigation system ; on the other hand, solve the accumulation of inertial navigation error and large drift problem ofs ingle inertial navigation. At the same time, adding the Beidou navigation system improve s the safety of navigation system.
