Multi-Channel Image Transmission (Network Transmission) Data Link
Product profile and purpose
This measurement and control data link system includes airborne mobile equipment and fixed equipment on the ground. It is used to establish wireless link between the airborne mobile equipment in the air and the fixed equipment on the ground, and make real-time display of the dual-channel image on display screen of the fixed equipment on the ground. The fixed equipment on the ground sends dual-channel bi-directional RS-422 signal, connects to on-board equipment, and is used to control their respective servo gear. In the meantime, it provides one-channel stable bi-directional headset call. Both the airborne mobile equipment and the fixed equipment on the ground are equipped with independent power supply and backup power supply for long operating hours.
