Abstract： In order to realize the response of artificial weather modification conveniently and accurately， a intelligent mobile terminal based on Android was proposed. The overall frame， main function and operation process of the system was introduced in detail. Meanwhile， some of the key technology of sending and receiving of basic instructions， application of mobile GIS platform， video information transmission， such as self-adaptive heartbeat bag， raster data transmission and display， terminal GIS coordinate transformation， cutting and optimization of video encoder， stream media transmission optimization and error control were emphasized. The result of preliminary application tests showed that the features and superiorities of this system were all obvious.
