How do I calibrate RTK dual-antenna direction finding in high-EMI environments?
In areas with high electromagnetic interference (such as iron mines or power grids), standard compass calibration is prone to failure. Aero-Titan is equipped with a Here 3 dual-antenna RTK system. Before powering up, switch the heading source to 'GPS_YAW' in the Ground Control Station (GCS) and disable the magnetic compass. Keep the aircraft stationary for at least 45 seconds on an open surface before takeoff until RTK shows 'FIXED' status to establish compass-free high-precision direction finding.
What adjustments are needed for high-altitude (5,000m AMSL) propeller matching & ESC tuning?
Low air density at high altitudes reduces lift at normal RPMs. Our platforms feature active air pressure auto-compensation. Prior to high-altitude missions, swap standard props for high-pitch carbon fiber propellers (e.g., from 22-inch to 24-inch). Upon power-on, the autopilot sensors log the barometric pressure and adaptively increase the FOC ESC speed-controller gain (D-Term Gain) to prevent flight response sluggishness or altitude wobbling.
How can I verify the Human-in-the-Loop (HITL) emergency override and parachute linkage?
Safety and non-destructive reclamation are our core values. Before BVLOS operations, perform a static safety-pin check. Without propellers installed, power the platform and trigger the emergency parachute channel on your transmitter (Channel 8 by default). The C3/C4 autopilot should instantly cut motor power and send an electrical release signal to the mechanical parachute lock. Once confirmed, manual lock closure and safety pin re-insertion can be safely conducted.
