78 Z-Family Technical Reference Manual
When turned off, the parameters entered via $PASHS,ANT are ignored and the
position is the position of the phase center of the antenna. This implies that the base
position entered should also be the one of the phase center of the base antenna.
Example: Set antenna reduction mode to CPD only:.
$PASHS,ANR,CPD <enter>
Antenna Reduction, when performed, is applied to ALL position messages except for PBN and the
position in the B-file. For more detail on the usage of the antenna reduction mode, see ”Base Station
Antenna Offset” on page 37 of Z-family manual.
ANT: Set Antenna Offsets
$PASHS,ANT,f1,f2,f3,m1,f4
Sets the antenna offsets from ground mark to antenna phase center via a reference
point. Horizontally, the reference point is the physical center of the antenna housing.
Vertically, the reference point is the point to which the antenna slant height was
measured. the antenna phase center is the center of reception of the signal.

Parameter Description Range
s Reduction Mode ON => Antenna Reduction on ALL position messages for
Autonomous, Code Differential, and RTK.
OFF => No Antenna Reduction in ANY position messages
for Autonomous, Code Differential, and RTK.
CPD => NO Antenna Reduction on for position messages for
Autonomous and Code Differential, but RTK has
antenna reduction. (default to be compatible with UB00)
