12 Glossary
A
A+ line
A guidance line you define on your field. The A+ line is defined fixing a point, then heading in a
direction. Guidance lines are for use with automated steering.
AB line
A guidance line you define on your field. You set a beginning point (A) and an end point (B). You use
guidance lines for use with automated steering.
Accelerometer
A device that measures non-gravitational acceleration.
Aggressiveness
The measure of how strongly the system makes steering changes.
Autonomous GNSS positioning
Autonomous GNSS positioning uses no corrections. The rover receiver calculates its position using
only the GNSS signals it receives. This method does not have high absolute accuracy, but the
relative accuracy is comparable to the other methods.
RTK GNSS positioning uses the RTK positioning method to achieve centimeter-level accuracy. To use
the RTK method, you must first set up a base station. The base station uses a radio link to broadcast
RTK corrections to one or more rover receivers.
B
Boundary
A line indicating the border surrounding a field.
C
CenterPoint™ RTK for radio
Positioning correction service for radio communication systems. Requires access to a base station
located within a eight-mile radius (approximately) from your farm. An RTK base station sends
corrections via a radio transmitter to a mobile receiver attached to your vehicle. Works well for
farms within 8 miles of an established RTK base station or base station network, without line-of-
sight obstructions such hilly terrain or an abundance of trees.
