Example: Set RAIM mode to terminal mode.
$PASHS,AIM,TER<Enter>
ALT: Set Ellipsoid Height
$PASHS,ALT,f
This command sets the ellipsoidal height of the antenna. Where f is the height in
meters, and the range is ±99999.99. The receiver uses this data in the position
calculation for 2-D position computation, and when in differential base mode.
Examples: Set antenna height to +100.25 meters
$PASHS,ALT,+100.25<Enter>
Set antenna height to - 30.1 meters
$PASHS,ALT,-30.1<Enter>
ANT: Set Antenna Offsets
$PASHS,ANT,f1,f2,f3,m1,x1
Sets the antenna offsets from reference point to antenna phase center.
The implementation of this command affects message type 1, 9, 31, 34, 3, and 22 significantly. Only
vertical offsets are supported by Message 22, thus the horizontal azimuth and distance fields of this
command should always be 0 if in RTK or differential mode.
Example: Set antenna offsets.
$PASHS,ANT,1.678,0.1737,0.5,0000.00,0.0<Enter>
