– "GPS/GLONASS GLIDE 2"
When a SMART-6L DGPS/GLONASS receiver is connected:
– EGNOS/WAAS
– EGNOS/WAAS + GLIDE
– GLIDE
– RTK radio (RTK license required )
– RTK GSM (RTK license required )
– TerraStar (RTK or L band licence required)
Information for GLIDE
If you have selected a correction signal with GLIDE, please note:
▪
Switch the GPS receiver off when driving on roads.
▪
After starting the systems each time, it takes ca. 5 minutes until the system is ready for
operation. Wait on the field to be worked during this time, before you start working.
▪
Ensure that the GPS receiver does not lose the GPS signal during work. If the signal gets lost, it
can cause the GLIDE to restart. This can lead to track offset.
Information for TerraStar
If you have selected "TerraStar" as a correction signal, please note:
▪
There are two different TerraStar correction signals: TerraStar-C and TerraStar-L. These differ
mainly in their accuracies.
▪
The accuracies are available ca. 5 to 10 minutes after switching on the GPS receiver under the
open sky.
▪
If the GPS signal fails due to shadowing by buildings or trees, the full accuracy is available again
at the latest after ca. 5 minutes. For this reason, you should avoid driving along rows of trees or
buildings.
▪
During the convergence, the GPS receiver and the vehicle should not be moved and the location
should not be changed.
Baud rate of the receiver on port B
Only appears when the "RTK radio" correction signal is selected.
If you are using a GPS receiver with a radio modem from a third-party manufacturer, the baud rate
must be adjusted in some cases. The baud rate must then correspond to that of the radio modem.
The baud rate for radio modems manufactured by Mueller Electronics is always 19.200 baud.
Correction during RTK failure
This parameter is only required if you are using the SMART-6L DGPS receiver with a steering
system.
Potential values:
▪
automatic
The parameter is activated.
When there is an RTK failure, a deviation arises between the current position of the vehicle and
the GPS position.
If the parameter is set to "automatic", you prevent the vehicle from driving directly to the new
GPS position. The system will then gradually steer towards the new GPS position. This prevents
the occurrence of large track offsets in case of RTK failure.
