Command
Set Antenna Height
$PASHS,ANH
This command sets the antenna height. The command structure is
$PASHSANH,x.xxxx
where x.xxxx is the height in meters. Maximum value is 6.4000.
Example: Set antenna height to 2.0000 meters
$PASHS,ANH,2.0000
Set Antenna Offsets
$PASHS,ANT
This command sets the antenna offsets from a reference point to the antenna phase
center. Slant is measured from the reference point to the antenna edge. Radius is the
distance from the antenna phase center to the antenna edge. Vertical offset is the
offset set from the antenna phase center to the antenna ground plane. Horizontal
azimuth is measured from reference point to antenna phase center, with respect to
WGS84 north. Horizontal distance is measured from the reference point to a point
below or above antenna phase center.
The command structure is $PASHS,ANT,f1,f2,f3,d4f4,f5*crc where each field is as
defined in Table 4.4.
Example: Set antenna height, radius, phase center, horizontal azimuth,and distance:
$PASHS,ANT,1.678,0.1737,0.0,0000.00,0.0
