Description
The device currently assigned to the selected
port within the active working style. The
device which is selected determines the
availability of the next fields.

If a mountpoint was selected from
a downloaded source table during
the use of the RTK connection wiz-
ard, then the RTK format which is
used with the NTRIP mountpoint is
displayed.
The proprietary Leica real-time GNSS data
format supporting GPS L1/ L2/ L5, GLONASS
L1/L2, Galileo E1/E5a/E5b/AltBOC and BeiDou
B1/B2. This format is recommended when
working exclusively with Leica instruments.
The proprietary Leica real-time GNSS data
format supporting GPS L1/L2 and GLONASS
L1/L2. This format is recommended when
working exclusively with Leica instruments.
CMR and CMR+ are compacted formats used
to broadcast data for third-party instruments.
Message according to RTCM version 2.x.
Uncorrected carrier phase and pseudorange.
Message 3 is also generated. Use for real-
time operations where the ambiguities are
resolved at the rover. Accuracy at the rover:
1 ‑ 5 cm rms after a successful ambiguity res-
olution.
Use RTCM when rover units from a different
manufacturer are used.
Use to decode the standard RTCM v3 and
the RTCM v3 (MSM) messages from the
base.
Message according to RTCM version 3. A new
standard format for transmission of Global
Navigation Satellite System correction infor-
mation. Higher efficiency than RTCM v2.x.
Supports real-time services with reduced
bandwidth.
Message types for real-time GNSS opera-
tion:
1001: L1-only GPS real-time observables
•
• 1002: Extended L1-only GPS real-time
observables
1003: L1 & L2 GPS real-time observables
