ELM: Raw Data Elevation Mask
$PASHS,ELM,x
Sets the value of elevation under which the measurement data (MCA) for that satellite
will not be output or recorded into data storage memory, where x is the elevation
mask in degree. The default is 5°.
Example: Set elevation mask to 10 degrees
$PASHS,ELM,10
ELM controls the elevation mask for satellites used for raw measurement output, and Base station
output of RTCM messages Type 18 & 19.
PEM controls the elevation mask for satellites used for position computation, and Base station
output of RTCM messages Type 1,9,31 & 34.
EPG: Set Kinematic Epoch Counter
$PASHS,EPG,d
Sets the initial value of the counter of epochs for recording at a site where d is the
number of epochs and ranges from 0 to 999. The command is used during kinematic
surveys, when you want to occupy a site for a set amount of time. When the number
of epoch goes to zero, the site name will be set automatically to ???? indicating that
the receiver is in motion.
Example: Sets the epoch counter to 20.
$PASHS,EPG,20<Enter>
The site name must be set with the $PASHS,SIT command before the epoch counter works.
EXF: Set Frequency Input
$PASHS,EXF,s
This command sets internal/external reference frequency input, where s is either ON,
OFF or an external frequency value in Hz.
