4.1 Sensor Correction

In case of sensor inaccuracies caused by disturbances in the EM field

we can recalculate the azimuth using our correction algorithm.

You can choose to do correction using four or eight points.

Four point algorithm has a maximum deviation of +/- 45 degrees.

Eight point algorithm has a maximum deviation of +/- 22 degrees.

You will need to experiment and see which option works best in your

case.

Before proceeding you will need:

1. Paper and pen to write the measured values down.

2. A regular compass for real world reference points.

The sensor should be attached to the boom in the same way it is going

to be used.

Do not open the sensor correction window before doing the

measurements because it will prevent you from using the RG app.

You will need your app to move your antenna.

Four Point Sensor Correction Procedure:

1. Rotate the antenna to actual North. Write down the value the

sensor reads in this position.

2. Rotate the antenna to actual East. Write down the value the

sensor reads in this position.

3. Rotate the antenna to actual South. Write down the value the

sensor reads in this position.

4. Rotate the antenna to actual West. Write down the value the

sensor reads in this position.

5. Open the Sensor Correction menu.

6. Tick Active box.

7. Select Four points.

8. Enter the values to the corresponding boxes.

9. Press Save.

Rotator Genius will now take into account the real world values and

recalculate the azimuth accordingly.

You can uncheck the Active box at any point to revert to raw sensor

data.

Eight Point Sensor Correction procedure works exactly the same with

additional values for NE, SE, SW, NW.
