Each light bar will show different information for the position of the bucket:
A vertical light bar (top) provides corrections for the cut and the fill (13). This light bar displays information for the lowest bucket tip relative to the design.
The horizontal light bar (center) indicates the left and right corrections to the horizontal guidance line for the bucket tip that has focus (14) .
A vertical light bar (bottom) indicates in and out corrections to the horizontal guidance line from the bucket tip that has focus (15) .

Pitch Sensor
The AccuGrade System uses a single axis angle sensor in order to measure the pitch of the machine.

Pitch SensorFront Linkage Sensors (Angle Sensors)
The AccuGrade System uses three single axis angle sensors that are located on the boom, the stick and the bucket linkage in order to calculate the position of the cutting edge of the bucket.

Angle SensorsFront Linkage Sensors (Position Sensing Cylinder and Rotary Sensors)
The AccuGrade System uses two Rotary Position Sensors that are located on the boom and the stick in order to measure the relative rotation angle between the two linkages.The Position Sensing Cylinder (PSC) measures the rod extension/retraction of the hydraulic cylinder for the bucket. The PSC uses a sensor that is integrated into the cylinder in order to make this measurement.

Refer to the following list for the type of location sensor that is used by the AccuGrade System:
MS990C ReceiverBoth Receivers are able to calculate their location by using information that is broadcast from GPS satellites that are orbiting the earth and correction signals that are sent from a base station. The MS990C receivers will also use information that is broadcast from GNSS satellites if a GNSS base station is used.Other Components
