Parameter correction of unmanned aerial vehicle based on beidou/inertial navigation and multi-sensor fusion
orientation and inaccuracy of UAV in the process of UAV flight
a method of parameter correction for UAV based on Beidou/Inertial navigation and multi-sensor is proposed. The parameters of pressure sensor and speed sensor are introduced in the Beidou/inertial navigation system
and combined with Kalman filter algorithm to calculate the optimal positioning value. The specific parameters are given to the inertial navigation system by the speed sensor
and the UAV trajectory is predicted by the relationship between the acceleration and declination. The optimal value is calculated by combining the current positioning parameters of the Beidou system
and the calculated UAV parameters are transmitted through wireless communication to the terminal for storage and display. The results show that the method of multi-sensor fusion is effective to improve the accuracy of flight trajectory and attitude
and the positioning accuracy is 3 m
which provides a powerful theoretical basis for handling UAV.
