Design of Wireless Location System Based on Beidou Short Message
Aiming at the problem of low recovery efficiency of aircraft,a positioning system designed by global satellite posi-tioning technology and Beidou short message communication technology is proposed.The system uses Beidou and GPS dual-mode hybrid positioning,and the positioning information is transmitted to the ground receiver through Beidou short message.The ground can obtain the location of the landing point according to the protocol solution,and the landing point search is completed.This design takes the Beidou module and dual SIM card switching communication as the core,including the main control module,power man-agement module,Beidou module and information processing module,etc.,to ensure the reliability of the system and reduce the power consumption of the system.The test results show that the communication success rate of the positioning system is more than 95%,and the positioning accuracy is better than 10 m,which meets the design requirements and has a good application prospect.
