Antenna 2
: [checkbox] Select ON when using a second GNSS antenna. Note that
the use of a second antenna is optional, but a second antenna is required for com-
passing functionality. Also note that the offset of antenna 2 is relative to antenna 1,
not to the VersaPNT X-Y-Z etching (see illustration below).
Antenna 2 Offset X
: [m] The relative X-offset from antenna 1 to antenna 2.
Antenna 2 Offset Y
: [m] The relative Y-offset from antenna 1 to antenna 2.
Antenna 2 Offset Z
: [m] The relative Z-offset from antenna 1 to antenna 2.
The antenna 2 uncertainty settings indicate how accurate the actual distances could
be measured.
Antenna 2 Uncert X
: [m; default=0.0254] Uncertainty in the Antenna Offset X
measurement.
Antenna 2 Uncert Y
: [m; default=0.0254] Uncertainty in the Antenna Offset Y
measurement.
Antenna 2 Uncert Z
: [m; default=0.0254] Uncertainty in the Antenna Offset Z
measurement
VersaPNT can be connected to one or two GNSS antennas., depending on the model type.
When selecting antenna installation locations, make sure that the following requirements
are met:
the view of the sky is unobstructed
the antennas are located on opposite ends of the vehicle, as far away from the Ver-
saPNT unit as possible, but the antenna cables are not longer than necessary.
The X-Y-Z distances between the first antenna and the X-Y-Z etching on the lid of the Ver-
saPNT unit, as well as the distance between the second antenna and the first antenna are
referred to as offsets and need to be configured under the
Calibration
tab. The illus-
tration below shows an example configuration:
