Autel Error Code 102310 indicates that the aircraft’s central flight controller has detected an irreconcilable conflict among its navigation sensors—specifically between the Global Navigation Satellite System (GNSS/GPS), the electronic compass (magnetometer), and the Inertial Measurement Unit (IMU). When these data sources disagree, the aircraft cannot safely determine its geographic position, velocity, or heading. The flight controller disables autonomous features and drops into manual Attitude (ATTI) mode.
Fast Fix
Move the drone at least 30 feet away from reinforced concrete, metal structures, and parked vehicles. Place it on a flat, level surface, power cycle the battery, wait until the app confirms at least 12 connected satellites, and perform both an IMU calibration and a compass calibration via the Autel Explorer app.
Quick Safety Snapshot
- Severity: High (disables GPS positioning and automated return-to-home; drone will drift with the wind)
- Safe to Fly: No
- Primary Cause: Localized electromagnetic interference, launching over steel rebar, uncalibrated IMU zero-biases, or satellite multipath errors
- Immediate Action: If this warning triggers mid-flight, immediately take manual stick control to counter wind drift. Bring the aircraft to a safe area and land.
What Error 102310 Means
Safe multirotor navigation requires sensor fusion. The flight controller runs an Extended Kalman Filter (EKF) that combines three independent sources of spatial data:
- The GNSS Receiver: Measures latitude, longitude, altitude, and ground speed via satellite signals.
- The IMU: Measures angular velocity (gyros) and linear acceleration (accelerometers) hundreds of times per second.
- The Compass: Measures absolute magnetic heading relative to Earth’s magnetic field.
Under normal conditions, all three sensors agree. For example, when the drone flies forward, the IMU registers forward acceleration, the GPS registers increasing forward velocity, and the compass confirms the nose is pointed forward.
If the compass is distorted by nearby rebar and reports a heading 60 degrees off from the GPS velocity vector, the EKF filter rejects the solution. To prevent the drone from aggressively correcting toward an incorrect heading, the flight controller flags Error 102310 and switches to ATTI mode.

Metal
1. Compass Flags Abnormal
If the compass health bar is yellow or red, or the app warns of magnetic interference:
- The launch surface contains ferrous metal (rebar in concrete, underground iron pipes, or metal manhole covers).
- Moving the aircraft to natural ground resolves the error without recalibrating. If calibration is needed, see Autel Error Code 102030 Compass Calibration Failed.
2. IMU Initialization or Bias Warning
If the IMU bias indicators are flagged:
- The drone was moved while powering on, or the IMU was calibrated on an uneven surface.
- Step through Autel Error Code 102020 IMU Initialization Error.
3. Satellite Signal Fluctuations
If the satellite count is low (<10) or fluctuating rapidly:
- You are operating in an “urban canyon” between tall structures, creating multipath errors where satellite signals bounce off buildings before reaching the drone.
- Move to an open area with an unobstructed view of the sky. For GPS diagnostics, review Autel Error Code 102000 GPS Signal Weak.
Step-by-Step Troubleshooting
Step 1: Move Away from Structural Interference
- Power down the drone.
- Pick up the aircraft and relocate at least 30 to 50 feet away from concrete pads, asphalt with slag aggregate, chain-link fences, and vehicles.
- Set the drone down on grass, dirt, or a non-metallic landing mat.
- Power on the aircraft and monitor the status indicator. In many cases, clearing the localized magnetic anomaly immediately clears Code 102310.
Step 2: Calibrate the IMU on a Cold, Level Surface
If the navigation error persists on clean ground, recalibrate the IMU to provide the navigation filter with stable reference axes:
- Ensure the drone is completely cool.
- Place it on a verified level surface.
- Open Autel Explorer -> Settings -> Flight Control -> Sensor Status -> IMU Calibration.
- Complete all six calibration orientations as guided by the app graphics.
Step 3: Calibrate the Compass in an Open Field
Once the IMU is calibrated, register a clean magnetic baseline:
- In the Sensor Status menu, select Compass Calibration.
- Hold the drone horizontally and rotate your body 360 degrees until the app chimes.
- Point the aircraft camera downward (or sideways as prompted) and rotate 360 degrees again.
- Confirm that the app displays “Calibration Complete” and that the compass interference bar returns to green. For general compass procedures, consult Autel Error Code 102003 Compass Error.
Step 4: Verify Home Point Acquisition Before Launch
- Do not arm the motors until the GPS indicator turns green, reports at least 12 satellites, and the app verbally confirms: “The Home Point has been updated.”
- Launching while the navigation system is resolving satellite ephemeris data frequently causes Error 102310 within the first 30 seconds of flight.
Managing In-Flight ATTI Mode Drops
If Error 102310 occurs while airborne:
- The drone will not hold horizontal position. When you release the control sticks, the drone will coast with the wind.
- Altitude hold remains active. The onboard barometer will maintain altitude as long as vertical throttle is centered.
- Fly the aircraft manually. Gently counter wind drift using the right stick (pitch/roll), steer the drone back to your position, and land manually. For techniques on manual flying, review Drone Entering ATTI Mode: Why It Happens and How to Fly.
Hard Stops: When to Ground the Aircraft
Do not take off if:
- Error 102310 remains active after completing both an IMU and compass calibration in an open field.
- The drone attempts to drift in widening horizontal circles when hovering (known as the “toilet-bowl effect”). This indicates an active heading-to-GPS calculation conflict; land immediately. For broader navigation fault logic, see Autel Navigation System Error Code.
- The sensor health screen displays constant hardware failure flags for the internal magnetometer or accelerometer buses.
