To realize the precise localization of the field working machine, the localization system which based on Laser/ Inertial Sensors (Laser/INS) was designed. Meanwhile, the system model was established, the Extended Kalman Filtering (EKF) algorithm was proposed, and the simulation was accomplished by Matlab. The simulation results show that the location system using the filter algorithm can keep precise...
A precise navigation method for high altitude unmanned aerial vehicle was researched. Strapdown inertial navigation system (SINS), star sensor and Bei Dou receiver were adopted in this method. Errors of SINS and misalignments of star sensor were chosen as system states of integrated navigation. A specified attitude matrix was constructed by outputs of SINS, then measurements of integrated navigation...
