Instruction Manual

– Reference Position: Specify the physical point on the
base system for which the receiver will generate
corrections. The three possible choices are: Antenna
L1 phase center, Antenna Reference Point (ARP) or
Ground Mark.
– Measurement Type: Specify the method that was used
when setting up the base system to measure the height
of the GNSS antenna (Vertical or Slant Height).
– Antenna Height: Value of base antenna height,
expressed in the selected distance unit, as measured
according to the specified measurement method.
– Receiver Antenna: Specify the model of GNSS antenna
used by the receiver. Select “UNKNOWN” if you don’t
know which model is used.
– Antenna Radius: In case of a “Slant Height”
measurement, enter the antenna radius (this is a
manufacturer specification), taking care to enter this
parameter in the selected distance unit. See also the
diagram below for more information.
– SHMP Offset: In case of a “Slant Height” measurement,
enter the SHMP offset (this is a manufacturer
specification) taking care to enter this parameter in the
selected distance unit. See also the diagram below for
more information.
NOTE: The Antenna Radius and SHMP Offset fields are
automatically preset to the right values when you
select an antenna type in the Receiver Antenna field.
– Virtual Antenna: This option is used to emulate a GNSS
antenna other than the one really used.
