Abstract

The traditional control system cannot determine the specific location of the transmission error of navigation information, the implementation process is complex, and the information sequence needs to be fed back to the source, resulting in reduced transmission efficiency and high delay of navigation information, so that the control effect is unsatisfactory. To this end, a GIS intelligent navigation information control system for micro air vehicle (MAV) is proposed. The BER calculation equation is designed and the principle of turbo encoder is analysed. The pseudo-random sequence is used to process the intelligent navigation information of the MAV to form an intelligent navigation information sequence. Without feedback to the source, the output information sequence can be dispersed due to the error code of sudden interference. Through the MAP method, the absolute value of the posterior probability ratio is regarded as the soft decision output, the code is used to obtain the error position and the transmission error of the intelligent navigation information is controlled, so that the design of the GIS intelligent navigation information control system for MAV is completed. The experimental results show that the improved system can better control the transmission error of navigation information, and the control effect is very satisfactory.
