Additional signals from modernised GNSS and a full constellation of emerg-

ing satellites such as BeiDou and Galileo will further increase measurement
performance and accuracy.
Three positioning modes are available:
2
Reference Station: This mode is designed for monitoring the stability of
-
the antenna position of a reference station. It is optimized for long
baselines as used within RTK networks. Movements will be detected
with a high reliability while the positioning results are smoothed to
prevent outliers from triggering false alarms.
Monitoring: In this mode the position calculation is optimized for moni-
-
toring applications with short baselines. Positioning results are less
smoothed than in Reference Station mode as outliers are less likely.
Therefore, a position change may be detected slightly faster than in
Reference Station mode.
Network RTK: In this mode the position calculation will behave as on a
-
real rover.
