SOM,NAV: Navigation Data Mask
Function This command is used to mask the signal observations that
are not consistent with the relevant navigation data. 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.
