ELM: Elevation Mask for Raw Measurements Outputs
$PASHS,ELM,d1
This command sets the minimum elevation for the output of raw measurement data
(CT1, MBN, MCA, etc.), where d1 is a number between 0 and 90. The receiver can
be set to output raw measurement data for each satellite it is tracking that is above
the elevation mask. It stops outputting raw measurement data for any satellite (GPS
and/or SBAS) at or below the elevation mask. If the elevation mask is set to 10°,
the receiver outputs raw measurement data for all tracked satellites with an
elevation of 11° or higher, but not output raw measurement data for any tracked
satellites with an elevation of 10° or lower. You can view the current raw data
elevation mask setting $PASHQ,RAW and checking the ELM field.
The ELM command sets the elevation mask for both GPS and SBAS satellites.
Examples
Enter the following command to set the elevation mask at ten degrees:
$PASHS,ELM,10
Enter the following command to set the elevation mask at fifteen degrees:
$PASHS,ELM,15
GGB:GGB Position Data
$PASHS,RAW,GGB,c1,s2,f1
This command enables or disables the position data (GGB) messages, where c1
is port A, B or C, s2 is ON or OFF, and f1 is the optional numeric output interval
setting supporting a range of 0.05 to 999 seconds, depending on the measurement
update rate option installed.
$PASHQ,GGB,[c1]
This command queries for one GGB position data. c1 is the optional port designator
for the response. If a port is not specified, the receiver sends the response to the
current port.
If the command is set without a period, the DG16 uses the period set by the
$PASHS,RCI command If the $PASHS,RCI command is issued after this message
period has been set, the period resets to the RCI setting.
