Satellite and fix computation related settings
It is possible to set up satellite and fix computation related settings such as elevation mask,
HDOP and PDOP limit in the setup file.
ELEVATION MASK 10 [deg]
The limit for minimum satellite elevation allowed in the
fix computation is default set to 10 degrees.
HDOP LIMIT 4
PDOP LIMIT 100
If the HDOP or PDOP value exceeds the set limit, no
position or velocity fix is computed.
The HDOP limit is default set to 4, while the PDOP
limit is default set to 100.
3.9.8
Height aiding
HEIGHT AID 2
It is possible to select which height aiding mode the system
should use. The parameter HEIGHT AID selects the aiding
mode. Four modes can be selected:
0: No height aiding.
1: Use value of AIDED HEIGHT as a constant height.
2: Use automatic filtered height aiding where initial
height is selected from a
pre-configured geoid model (STANAG 4294).
3: Use automatic filtered height aiding with AIDED
HEIGHT as initial value.
Note
If the pre-configured geoid model file is not
found, mode 3 is used.
It is recommended to use mode 2.
AIDED STDV 100.0
AIDED HEIGHT 0.0
The AIDED HEIGHT parameter is an initial value for
filtering height. The value is the antenna height above the
WGS 84 ellipsoid. When using HEIGHT AID mode 1, 2 or
3, it is very important that the antenna height input is
correct. If the value is wrong, the position will be unstable.
