ProFlex 800 CORS Station
(Clicking on the Get current position button assigns the
last position computed by the receiver to the reference
station as its reference position.)
• Set the GNSS antenna parameters:
– Reference Position: Specify the physical point of the
CORS station for which the receiver will collect data.
The three possible choices are: Antenna L1 phase
center, Antenna Reference Point (ARP) or Ground
Mark (reference point).
– Measurement Type: Specify the method that was used
when setting up the CORS station to measure the
height of the GNSS antenna (typically “Vertical” is
used, “Slant” being most of the time used for
temporary base setups on tripods).
– 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.
– 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.
– Virtual Antenna: This option is used to emulate a GNSS
antenna other than the one really used (typically
ADVNULLANTENNA is used).
Choosing a virtual antenna different from the one really
used affects the raw and differential data as if they had
