RTK enabled and functioning properly:
Vertical: ±0.1 m; Horizontal: ±0.1 m
RTK disabled:
Vertical: ±0.1 m (with vision positioning); ±0.5 m (with GNSS positioning)
Horizontal: ±0.3 m (with vision positioning); ±1.5 m (with GNSS positioning)
The position of the camera center is relative to the phase center of the onboard D-RTK
antenna under the aircraft body's axis: (36, 0, and 192 mm) already applied to the image
coordinates in Exif data. The positive x, y, and z axes of the aircraft body point to the
forward, rightward, and downward of the aircraft, respectively.

First-Fixed Time: < 50 s
Positioning Accuracy: Vertical 1.5 cm + 1 ppm (RMS); Horizontal 1 cm + 1 ppm (RMS).
1 ppm indicates error with a 1 mm increase over 1 km of movement.
Velocity Accuracy: 0.03 m/s
Mapping accuracy meets the requirements of the ASPRS Accuracy Standards for Digital
Orthophotos Class III.
