Dear all,

May I know if i increase the separation height difference of anchors to 10 meters, does it help to improve z axis accuracy?

Why is that we cannot estimate z axis if all the anchors are in the same height? Any suggested readings?

Thanks!
Sam

Hi Sam,

The main reason why putting the anchor at different height helps Z accuracy is the dilution of precision: https://en.wikipedia.org/wiki/Dilution_ ... avigation)

On a side note, if all anchors are in the same plan there is two possible position for the measurements so the position estimator can get confused.
