Technical Data

Type
Static with long observa-
tions
Type
Single Baseline (<30 km)
Network RTK
Tilt compensated in real-time
Additional Hz pole tip uncertainty:
Typically less than 8 mm + 0.4 mm/° tilt down to 30° tilt for topographic
points (not for static control points)
Typically 2 cm to 4 cm (2D) within the distance of 2 m to 10 m between the
camera and the object
The accuracy depends on the prevailing GNSS accuracy and the type of the
trajectoy.
A curve in the trajectory increases the accuracy of an image point measure-
ment.

Data (Leica GNSS raw data and RINEX data) can be recorded on the internal
memory or on the SD card.
1 GB is sufficient for over 1 year of raw data logging based on logging every
15 s from an average of 15 satellites.
