Tilt Offset Measurement

GNSS receivers usually comes with 2 measurement sensors (Tilt Sensor & Magnetic Sensor) to assist with tilted measurements (See Electronic Bubble section for more information)

The Tilt Sensor is more reliable and provides better accuracy compared to the Magnetic Sensor. This routine takes advantage of this, and only uses Tilt Sensor to Trilaterate a position what is difficult to survey without tilted pole measurement.

Two methods are available:

Two Pole Tilt Intersection
Three Pole Tilt Intersection

Two Pole Tilt Intersection

Make sure the button of the pole is at the same point

Measure Pole Tilt 1

Tilt the pole in one direction and Click this button to store the first tilt angle (Red Circle)

Measure Pole Tilt 2

Tilt the pole in the other direction and Click this button to store the first tilt angle (Green Circle)

There will be two intersecting points, choose Solution A or Solution B for the desired intersecting point, and click Save Point to Store it

Three Pole Tilt Intersection

Make sure the button of the pole is at the same point

Measure Pole Tilt 1

Tilt the pole in one direction and Click this button to store the first tilt angle (Red Circle)

Measure Pole Tilt 2

Tilt the pole in another direction and Click this button to store the first tilt angle (Green Circle)

Measure Pole Tilt 3

Tilt the pole in the last direction and Click this button to store the first tilt angle (BlueCircle)

There will be only one intersecting point, click Save Point to Store it
