Research on Integrated Navigation System of Small UAV Based on MEMS Sensor

This paper uses inertial sensor-based inertial navigation system to loosely integrate with satellite navigation systems based on Beidou and GPS to construct an integrated navigation system. The navigation prototype is designed and manufactured. Data fusion between the two navigation systems is accomplished by Kalman filter algorithm. According to the precision condition of MEMS sensor, inertial navigation system mechanization and error model are established. Compared with the industrial integrated navigation system, the experimental results show that the navigation system designed in this paper has good static and dynamic measurement accuracy.
