Mapping Accuracy ** Mapping accuracy meets the requirements of the ASPRS Accuracy Standards for Digital Orthophotos Class ?
** The actual accuracy depends on surrounding lighting and patterns, aircraft altitude, mapping software used, and other factors when shooting.
Ground Sample Distance(GSD) (H/36.5) cm/pixel?
H means the aircraft altitude relative to shooting scene (unit: m)
Data Acquisition Efficiency Max operating area of approx. 1 km² for a single flight(at an altitude of 182 m, i.e., GSD is approx. 5 cm/pixel, meeting the requirements of the ASPRS Accuracy Standards for Digital Orthophotos Class ?
Single-Frequency, High-Sensitivity GNSS Module GPS+BeiDou+Galileo*?Asia)?
First-Fixed Time?< 50 s
Positioning Accuracy: Vertical 1.5 cm + 1 ppm?RMS??
Horizontal 1 cm + 1 ppm?RMS?
1 ppm means the error has a 1mm increase for every 1 km of movement from the aircraft.
