What is the dual-channel training standard of UAV?

The dual-channel training standard of UAV is (1) lightweight design, which greatly reduces the antenna weight. (2) The DF antenna array with active antenna elements provides extremely high sensitivity. (3) Frequency division direction finding antenna array to further reduce the weight and the load of UAV. (4) Excellent amplitude-phase consistency and extremely low antenna cross-coupling influence can provide good direction finding accuracy. The direction finding antenna adopts the method of multiple (5) antenna elements and related interferometers, which has good anti-interference ability in practical environment. Even in the environment of a large number of reflected signals, the system can still provide accurate direction finding and strong anti-environmental interference ability. Smooth take-off and landing and hovering training, at least in the fixed-point mode, the micro multi-rotor UAV can take off and land vertically and smoothly, and the fixed-point hovering after take-off does not exceed one fuselage position; 2. Eight-sided hovering training: Turn the course to the left or right from the tail 0 degree, and hover the micro multi-rotor UAV at least 45 degrees in eight directions in a fixed way, with the deviation not exceeding1. 3. Pre-flight and post-flight inspection, including but not limited to the appearance of UAV system, fasteners, connecting wires, power supply, electronic equipment status, signals, etc. ; 4, flying sideways, capable students can level.
