The short-range terminal of RZ-90 missile ground image transmission data link compresses the image data of the terminal in real time, encodes and modulates it together with the data information, and sends it to the vehicle / ground terminal in the form of radio wave through the antenna. At the same time, the short-range terminal receives the control command of the vehicle / ground terminal and sends it to the short-range terminal computer. The product adopts large bandwidth, high-speed frequency hopping technology and networking technology. The system can accommodate at least 12 sets of on-board / ground terminals and corresponding short-range terminals at the same time.
