SDR 25km data transmission module
SDR 25km data transmission module
Product introduction
The SDR 25km data transmission module is mainly used for D-ground wireless communication. On the one hand, it can send remote control commands to control and command air platforms and air mission loads; on the other hand, it can also transmit the video images and telemetry data detected by D to ground equipment. The above display is for ground personnel to grasp the scene situation. The data link has the advantages of strong real-time performance, good reliability and high security, and is an important link to realize command automation.
Features
Two-way communication, real-time sending and receiving, electromagnetic compatibility of the whole system, anti-interception, anti-interference, system self-check
