Abstract：Aiming at the problem that it is difficult to field upgrade and maintain the Beidou terminal program in the current market,the thesis designs a remote upgrade scheme of Beidou terminal program on the basis of IAP. In the design,it systematically studies STM32 programme on account of the key technology of Internet access provider(IAP)and also puts forward the design con?cepts of breakpoint resume,TEA encryption and decryption and dual-link,which achieves the function of remote online real-time update of Beidou terminal program and greatly improves the stability in the process of transmission. Test shows that this scheme over?comes the shortcoming of Beidou terminal that hardware downloader is required to field upgrade the program and increases the stabil?ity of Beidou terminal program in the process of remote upgrade,which has practical significance for popularizing Beidou terminal.
