SOM,SNR: Signal-to-Noise Ratio Mask
Function
This command is used to mask the signal observations that
do not meet the minimum signal-to-noise ratio you specify.
This means that only the observations meeting this
requirement will be output (all the others will be rejected).
This mask is enabled only after the “User-defined” option (9)
has been selected with the $PASHS,SOM command.
Command Format
Syntax
$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
Parameter

receiver will assume s2=s1. “0” means no
mask.
0-60 dBHz 28
*cc
Optional checksum
*00-*FF
Raw Data Masked by f2
