The Autel EVO 2 RTK module provides real-time centimeter-level positioning data and supports Post-Processing Kinematic (PPK). The aircraft can record the original satellite observation data, camera exposure parameters and various other data. The positioning system supports A-RTK base station and RTK network, which helps to achieve accurate and stable data acquisition in complex operation environments.
Hovering Accuracy (When RTK is enabled and working normally):
Vertical: ±0.1 m; Horizontal: ±0.1 m
RTK is not enabled: vertical: ±0.1 m (when the visual positioning is working normally);
±0.5 m (when GNSS positioning works normally) Level: ±0.3 m (when the visual positioning is working normally);
±1.5 m (when GNSS positioning works normally)
Image Position Compensation:
The position of the camera center relative to the phase center of the airborne A-RTK antenna, under the body axis system: (-2.63, 0.31, 83.5) mm, and the photo EXIF coordinates have been compensated. The positive XYZ axis of the body axis system points to the front, right, and bottom of the aircraft respectively.
