Abstract:
To solve how to improve the positioning accuracy of the Beidou navigation systems terminal, we raise a Beidou positioning platform based on ARM+DSP architecture and displaying map via 4G signal. DSP is responsible for receiving Beidou signal which UM220-III has transmitted, and using the UKF algorithm to amend the positioning result. ARM receives the data DSP has processed ,and displays positioning information through the embedded QT program. It displays the network map via Baidu API function when there exists 4G signal, and uses mitab library to call the mif files to display the local map when there is no 4G signal. The experimental results show that the design can achieve the requirements of improving the positioning accuracy of the Beidou terminal.
Key words: ARM DSP architecture, UKF algorithm, 4G, mitab library, Baidu API function
