Firefighting Professional Mission Drone B (Tethered Drone)

• Model: Hexacopter with twelve rotors;
• Body craftsmanship: Foldable arm and propeller design for quick deployment and storage;
• Wheelbase: 1785±10mm;
• Propellers: 34-inch foldable propellers;
• Maximum payload capacity: 30kg (takeoff altitude ≤1000m);
• Maximum hovering height: 300m (takeoff altitude ≤1000m, payload ≤20kg);
• Tethered flight hover time: 12h;
• Maximum ascent speed: 3m/s, maximum descent speed: 2m/s;
• Direction finding capability: Uses dual-antenna positioning and direction-finding, capable of flying in complex magnetic field environments;
• Positioning accuracy: Horizontal position better than 1m (1σ), vertical position better than 1m (1σ), horizontal attitude better than 1° (RMS), heading attitude better than 1.5° (RMS);
• Positioning modes: BeiDou navigation, single-point positioning, fixed differential RTK, etc.;
• Control methods: Manual control and automatic control, supports one-button takeoff, one-button landing, one-button altitude change, one-button heading change;
• Sensor data collection: The drone flight controller can collect real-time status information such as onboard power voltage and temperature, and send it to the ground station monitoring software;
• Safety protection: Single propeller failure controlled protection, automatic protection on power failure, automatic protection on communication interruption;
