3.9.9 Range and age limit on reference stations
It is possible to exclude long distance reference stations from the position solution. This
option is useful when operating in areas with high ionospheric activity, e.g. in Brazil and
Africa. Optimum accuracy is achieved when the maximum distance to the reference stations
is less than 1000 km. When operating in other areas, the default configuration should be used.
DIFFCORR RANGE LIM 2000 [km]
The maximum range limit is 10 000 km. If a range
limit is set outside this limit,
10 000 km will be used.
Default range limit is 2000 km.
DIFFCORR AGE LIM 90 [s]
The maximum age of corrections can also be set in
the setup file. If the age exceeds the limit, the
correction is not included in the fix computation.
Default age is 90 seconds.
3.9.10 SBAS configuration
SBASLINK ENABLE LINK STATUS 1
When installing DPS 132, the SBAS link is default
enabled. The link shows the status of the SBAS
corrections in the TMS display.
SBASLINK NAME SBAS
It is possible to specify the link name which is
displayed on the TMS display. Default name is
SBAS.
SBASLINK DECODE PRN1 -1
-1: decode data from all geo satellites, PRN2 is
ignored XXX:decode data from geo satellite XXX
SBASLINK DECODE PRN2 0
0: decode data from PRN1 only YYY:decode data
from geo satellite YYY too
3.9.11 Differential correction settings
DCLNK2 TYPE SCF
It is possible to define several correction links in the DPS
system. The links can be set up to decode SCF
(Supercompressed format), RTCM (RTCM Sc-104 v2.2
format) or TOPNAV (DGPS and DVAR from Thales
receivers).
