90 Guidance, Leica mojoXact Plus
7 Guidance
Waypoints Waypoints are used to define a line in the field to which all working lines will be
parallel. Waypoints must be set before auto-steer can be used.
The mojoXact Plus supports AB Parallel guidance, A+ Heading guidance and Pivot
guidance.
How to set these types of waylines when the mojoXact Plus is used with a third-party
terminal is described below, along with wayline management, which includes, saving
the active wayline, loading a saved wayline, changing a wayline’s name, deleting a
wayline, deleting all waylines, exporting waylines to a USB memory key, importing
waylines from a USB memory key, and setting a field offset. The nudge feature which
allows the position to be adjusted to account for GPS drift over time is also described.
For information on how to set and manage waylines when the mojoXact Plus is used
with a Leica mojo3D, refer to the Leica mojo3D User Manual.
Pre-requisites for
setting a wayline Before a wayline can be set, the following pre-requisites need to be achieved:
• The mojoXact Plus should have been installed in accordance with the instructions
in Chapter "2 System Installation" and powered up as instructed in Section "3.1
Starting Up".
• If Network RTK is used as the GPS correction source, then the cell modem must
be set up and have a good connection status. Refer to Section "3.6.2 Cell Modem
Settings".
• The vehicle and implement (if applicable) must be set up, including terrain
compensation and mojoXact Plus orientation. Refer to Section "3.3 Initial Setup
Wizard" or Chapter "4 Vehicles and Implements".
• The GPS correction source must be configured and have a good connection
status. Refer to Chapter "6 Correction Sources".
• The GPS must have a good position fix as indicated by the symbol in the
Information Area of the main navigation screen. If the symbol displays then
there is a problem with the GPS connection that needs to be fixed before a
waypoint can be set.
7.1 AB Parallel Guidance
General informa-
tion
In AB Parallel guidance, working lines are parallel,
and are set by defining an initial waypoint (A) and
a final waypoint (B).
When the vehicle reaches the end of each working
line, the operator must disengage the auto-steer
(usually by turning the steering wheel or using the
auto-steer button) and turn the vehicle around
before engaging on the next working line.
