Abstract

In order to solve the problem of atmospheric parameter information loss or large error caused by climate and electromagnetic wave in atmospheric data system, a redundant fault tolerant design of UAV based on dead reckoning algorithm was proposed. The equipment redundancy and data fault-tolerant design methods are used to improve the stability of the equipment, and the fault-tolerant Kalman filter is used to improve the measurement accuracy of the data. The original atmospheric parameters read by the sensor are filtered and their errors are analyzed, and the weight of each sensor is obtained. Finally, the optimal data value is obtained by information fusion according to the weight. Experimental data show that this method can improve the measurement accuracy, fault detection and real-time fault tolerance of the data, and can meet the requirements of unmanned aerial vehicle autonomous flight.

Key words： atmospheric data; dead reckoning; redundant design; fault-tolerant design; data fusion
