Bedienungsanleitung - Setting a reference point

Setting a reference point

The coordinates of the GPS receiver are crucial when setting the reference point. If you do not want to dismantle the GPS receiver each time, you must always set the vehicle in the same position. This means that the GPS receiver is also in the same position.

When setting the reference point, you will require a fixed point whose position will not alter over time. For example, this can be a tree, a landmark or a manhole cover.

This point is required in order to position the tractor in exactly the same position for future GPS signal calibrations.

	NOTICE
	Data loss due to the lack of a reference point If you are unable to locate the reference point in the future, the recorded data will be unusable. 1. Always remember the precise position of the reference point for each field!

The illustration below shows a possible position of the tractor when setting the reference point:

	Distance between the GPS receiver and the X-axis point on the roadside		Distance between the GPS receiver and the Y-axis point on the roadside
	Line from a fixed permanent point over the road

Procedure

þ: When you are working the field for the first time.

1.: Find a fixed point at the entrance to the field. For example, this can be a tree, a landmark or a manhole cover.

2.: Draw a line from this point over the path on which the vehicle is standing.

3.: Position the vehicle with its two front wheels on the line.

4.: Write down the distance between the fixed point and the vehicle. You must also adhere to this distance when calibrating the GPS signal.

5.: Start a new navigation.

6.: Tap the following icons consecutively:

⇨: An “R” and a point appears on the terminal screen, marking the reference point on the field. The point is located beneath the arrow.

⇨: You have now set the reference point.
