Incoming data stream wizard: Configure real time in data stream

Background Information
This page is used to configure the receiving of real time correction messages for RTK and DGPS positioning.
Incoming real time streams can be used to calculate a fixed or DGPS position.
The calculated position can be streamed via an NMEA data stream and external applications such as Leica SpiderQC or Leica
GeoMoS can
be used to monitor the antenna movement and automatically generate alarms in case predefined thresholds are exceeded.
Three positioning modes are available:
Positioning mode Description
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 monitoring 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.
Receiving and sending RTK data works simultaneously for Reference Station and Monitoring mode.
In Network RTK mode, it is recommended to disable all outgoing real time data streams.
Depending on the length of the baseline, the accuracy of the position solution will vary. This means that with
longer baselines the reliability of detecting movements decreases.
If single site corrections are available only from distant sites, it is recommended to use network corrections
like MAX or i-MAX rather than single site corrections to improve the accuracy of the position calculation and
the reliability of detecting movements.
In order to obtain a fixed position, the following options are required:
- GRL114 Site Monitor
- GRL119 Dual Frequency
Without these options only DGPS positions can be obtained.
Using SBAS for DGPS does not require any option. However, all incoming data streams must be deleted if
SBAS should be used for the position calculation.
For activating an incoming Real time data stream, L2C tracking must be disabled for GPS and GLO.
