Features: - Tilt-compensated heading using quaternion-based orientation Roll and pitch compensation for uneven terrain - Magnetic declination correction: 1.5° for France - Heading normalization to 0-360 degree range - Publishes both Float64 (degrees) and quaternion representations - 10Hz publishing frequency with configurable parameters Algorithm: - Subscribe to IMU (quaternion orientation) and magnetometer data - Convert quaternion to roll/pitch/yaw for tilt compensation - Project magnetometer vector onto horizontal plane using trig functions - Apply declination correction and normalize heading - Publish heading as Float64 degrees and quaternion (Z-axis rotation only) Test Coverage: - 30+ unit tests covering: - Node initialization and parameters - Quaternion to Euler conversion (identity, 90° rotations) - Heading quaternion creation (0°, 90°, 180°, custom angles) - Tilt-compensated heading with roll, pitch, combined tilts - Declination correction application - Sensor subscription handlers - Heading angle normalization and wrapping - Realistic scenarios (level, tilted uphill/sideways, 3D tilt, weak signal, continuous rotation) Topics: -
