NTRIP caster, through two distinct mount points managed

• Programming the data generated by a base is addressed
separately (see
Defining the Data Generated by a Base on
page 69 and Rover Operating in Flying RTK Mode on
page 62 ).
General
Parameters
• Click on the
Base Setup
menu.
• Set the receiver parameters:
–
Dynamic
: Choose the type of motion that best suits the
base (static, quasi-static, walking, ship, automobile,
aircraft, unlimited, adaptive or user-defined).
Typically, a base is static.
–
Moving Position
: Enable this option if the base may be
moving while being operated. For all other cases where
the base always stays static, keep this option disabled.
–
Latitude, Longitude, Ellipsoid Height
: Use these three
fields only when the
Moving Position
option is disabled.
Use them to enter the reference position of the base
(three-dimensional geographical coordinates). The
coordinates shown in these fields are irrelevant and not
used when the
Moving Position
option is enabled.
Clicking on the
Get current position
button assigns the
last position computed by the receiver to the base as
its reference position. It makes no sense to use this
button when the
Moving Position
option is enabled.
• Set the GNSS antenna parameters:
–
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
