Tracking Threshold (SNR):
This parameter sets the minimum C/N0 threshold to track a satellite. Any GNSS satellite,
with C/N0 less than the threshold value is dropped and the engine searches for another
satellite with a stronger signal level. Increasing the tracking threshold decreases the
GNSS sensitivity, but helps prevent errors due to multipath. The value must be in the
range 10 to 40. The default is 10.
Positioning Threshold (SNR):
A satellite must have a signal strength above this threshold to be included in a fix
calculation. The default is 15, which helps reduce multi-path errors.
Default 2D DOPS
A low DOP value represents a better positional precision due to the wider angular
separation between the satellites used to calculate a unit's position.
These are the maximum allowable values for calculating a 2D fix.
Default 3D DOPS
:
These are the maximum allowable values for calculating a 3D fix.
Startup 2D DOPS
Set these values the same as the default 2D DOPS.
Startup 3D DOP
:
Set these values the same as the default 3D DOPS.

1 PPS TAB
1PPS Enable:
1PPS is output when set.
Invert 1PPS Polarity:
The polarity of the 1PPS output is inverted.
1 PPS Hold Position:
The configured Hold Position is used in Timing application as the current position.
