$PASHS,SOM,SNR,f1[,f2][*cc]
Parameters
Comments
• The $PASHS,SOM,SNR command can only mask
particular signal data for which the SNR does not meet
your requirement. If however at the same time the L1CA
data are disabled, then all the satellite observations will
also be masked.
• The $PASHS,SOM,SNR command equally affects all
GNSS systems and their signals, except GPS L1P(Y) and
L2P(Y). For these two signals, a hard-coded SNR
threshold is applied.
Examples
Setting SNR masks for both differential and raw data to
30 dBHz:
$PASHS,SOM,SNR,30*68
Enabling all signal observations to be output regardless of the
signal-to-noise ratio:
$PASHS,SOM,SNR,0*5B
