英文摘要	To transmit remote sensing images by BD short message system, a method that transmits changed images based on subdivision size of global subdivision grid (GSG) is introduced. Combining the facts of BD's short message bandwidth with the features of remote sensing image, it uses some policies, including transmitting remote sensing images based on subdivision cells, transmitting changed images and transmitting codes of objects. It also adopts retransmitting loss packets to increase the reliability of remote sensing images transmission. At last, it is verified by simulation system. The result shows transmitting remote sensing images by BD short message system based on GSG is available and is of theoretical and applied value.; Engineering, Electrical & Electronic; Telecommunications; CPCI-S(ISTP); 0
