$PASHS,SOMM,WRN
SOM,WRN: Channel Warnings Mask
Function
This command is used to mask the signal observations for
those signals flagged with channel warnings (MPC warning
bits are counted from 1 to 8). This means that only the
observations from non-flagged signals 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,WRN,s1[,s2][*cc]
Parameters
Comments
• A signal is considered as flagged in at least one of the
following cases:
– Carrier phase tracking is not stable (Bit 3 of MPC/MCA
warning is set).
– Pseudo-range data quality is bad (Bit 5 of MPC/MCA
warning is set).
– Polarity is not resolved (MPC/MCA Phase Tracking
Polarity flag is set to 0).
• The $PASHS,SOM,WRN command will mask only some
particular signal data (e.g. L1CA or L2P) corresponding to
a given satellite. If at the same time the L1CA data are
disabled, then ALL the satellite observations, and not only
those masked, will be rejected.
