4.4.3 DGNSS configuration
4.4.3.1 SBAS tracking
In the SBAS tracking view
it is possible to set up
Automatic or Manual
tracking of SBAS satellites.
When Automatic tracking is
selected, the GNSS receiver
chooses which SBAS
satellites to track.
In Manual mode the user
must set up which SBAS
satellites to use. If two
SBAS satellites are
selected, the system will
automatically select and use
data from the best satellite.
If only one SBAS satellite
is selected, only correction
data from this satellite will
be used in the
computations.
Figure 25 SBAS tracking view
If no specific SBAS satellite is selected, the system will select and use data from the
best of the available satellites.
If the selected SBAS satellite is not available, the system will not use the SBAS
correction data in the computations.
Maximum two SBAS satellites may be tracked by the GNSS receiver.
4.4.4 MRU configuration
4.4.4.1 MRU Geometry
The lever arm vector from the AP to the MRU location has to be measured or calculated
based upon drawings or previously measured points, and entered into the software.
Look at the sketch of the MRU geometry on the screen in order to enter correct signs on
the co-ordinates. Check also that the MRU has been located on the expected spot in the
vessel shape. If not, check the signs and the co-ordinates input for the MRU, the vessel
dimension and the entered location of AP.
