Configuration Tab
Antenna
Use this area to define the parameters of the antenna used
physically at the base, as well as a virtual antenna if
necessary. A virtual antenna may be defined to allow the base
to deliver raw data as if it were collected with this antenna.
See the description of each parameter in the table below.
“Get current
position” button
Click on this button if you want to allocate the last
position computed by the receiver as the reference
position for the base. As a result, the Lat/Lon/
Height fields below are updated with the coordi-
nates of this last computed position.
CPD,MOD
Latitude
Longitude
Ellipsoid Height
Latitude, longitude and ellipsoidal height defining
the reference position of the base. May be entered
manually or using the “Get Current position” but-
ton.
POS
Parameter Designation $PASHS
Reference
Position
Select one of the options below to define the
physical location of the base:
• L1 phase center
• Antenna Reference Point (ARP)
• Ground mark
ANR
Measurement
Type
Specify the type of measurement (“Slant” or “Ver-
tical”) through which the above antenna height
was measured.
ANH
Antenna
Height
Enter the measured antenna height according to
the measurement type used and the selected dis-
tance unit.
ANT or ANH
Receiver
antenna
Select the name of the antenna used at the base.
This antenna name can only be chosen from a list
of antenna names stored in the receiver.
UNKNOWN, NULLANTENNA, ADVNULLAN-
TENNA are special definitions of antennas typi-
cally used as virtual antennas.
ANP,OWN
Antenna
Radius
(Only if “Slant Height” measurement type
selected). Enter the antenna radius according to
the selected distance unit.
ANT
SHMP Offset
(Only if “Slant Height” measurement type
selected). Enter the vertical offset of the Slant
Height Measurement Point for the antenna used
by the rover. Take care to enter this parameter in
the selected distance unit. See also the Note
below.
