Message type Description
Leica
The proprietary Leica real-time data format supporting
GPS and GLONASS. This is the best format to use when
working exclusively with Leica Viva rovers or other Leica
rover units.
Leica 4G
Leica proprietary RT format supporting GPS (including
L5), GLONASS and Galileo. This is the best format to
use when working exclusively with Leica rover units
which support all available GNSS signals.
CMR
Compacted formats used to broadcast data for third
party receivers.
CMR+
Compacted formats used to broadcast data for third
party receivers.
RTCM 2.x (Type 1,2)
Differential and Delta Differential (Code) GPS
corrections. Use for DGPS applications. An accuracy of
0.5-5m rms can be expected at the Rover.
Additional messages sent: 3
RTCM 2.x (Type 2,9)
GPS Partial Correction Set and Delta Differential GPS
Corrections. Use for DGPS applications. An accuracy of
0.5-5m rms can be expected at the Rover. Use this when
a slow data link is being used in the presence of
interference.
Additional messages sent:3
RTCM 2.x (Type 18,19)
Uncorrected pseudorange and carrier phase
measurement. Use for RTK operations where the
ambiguities will be resolved at the Rover (RTK). An
accuracy of around 1-5cm (rms) can be expected after
successful ambiguity resolution.
Additional messages sent: 3, 22, 23, 24
RTCM 2.x (Type 20,21)
RTK Carrier phase corrections and high-accuracy
pseudo-range corrections. Use for RTK operations.
There is negligible difference in the accuracy obtained
using these messages as compared to messages 18
