Leica GR50 - Accuracy in Differential Phase Mode

GR30/GM30/GR50, Technical Data
64
Accuracy in
differential phase
mode
1
Additional signals from modernised GNSS and a full constellation of emerging satel-
lites such as BeiDou and Galileo will further increase measurement performance and
accuracy.
2
Might vary due to atmospheric conditions, signal multipath, obstructions, signal
geometry and number of tracked signals.
Note: The mentioned accuracy values for post-processing are based on using the
LEICA Geo Office. Using specialist scientific software (Bernese) available from Leica
Geosystems, the following accuracies can be achieved in static post-processing mode,
even on very long baselines:
