Command
Set Longitude of Antenna Position
$PASHS,LON
Sets the longitude of the antenna used in differential base mode. The command
structure is $PASHS,LON,dddmm.mmmmmmm,x where dddmm.mmmm is
longitude in degrees (ddd) and decimal minutes (mm.mmmmmmm), and x is E (East)
or W (West). The default is 0.
Example: Set antenna longitude to 12159.8291219° west
$PASHS,LON,12159.8291219,W

Item Description
SVS Y indicates satellites (SVs) the sensor will attempt to acquire (total of 32 SVs) .
Default is Y (yes).
PMD Position mode for the minimum number of satellites required to compute a position
fix. 0:With default value of 0, a minimum of 4 SVs is needed to compute a
position. Altitude is not held fixed.
1:When 3 SVs are locked, sensor holds altitude fixed. When more than 3 are
locked, sensor computes altitude.
2:Altitude is always held fixed regardless of number of locked satellites.
3:When 3 SVs are locked, sensor holds altitude fixed. When more than 3 are
locked, and HDOP is less than the specified HDOP mask, the sensor computes
altitude. When more than 3 SVs are locked, and HDOP is equal to or greater than
HDOP mask, the sensor holds altitude fixed.
Be aware that when the sensor is first turned on, the altitude is 0. If position mode
is set to 1, 2, or 3, enter a value for altitide in the POS field.
FIX Altitude hold fix mode to be used when computing a 2-D position. With default
value of 0, the most recent altitude computation is used.
PDP Position Dilution of Precision. Default is 40.
