Re: Max Distance Ranging

Thanks, let me check if the distance to the ground makes a difference.
Btw, is it also normal that the ranging offset changes according to where the tag is placed?
In my lab, I have access to a Vicon system in order to measure the actual distance.
1. If I attach the tag on the drone, and I place the anchor at a distance of 2m, I measure roughly 1.9m with LPS with a 0.1m offset.
2. However, if I place the tag on a cardboard box (as can be seen in one of the above images), I measure an offset of 0.5m.
3. If I change the immediate environment a little bit (for example moving the chair in the above image, while guaranteeing LOS condition), I realize that the range measurement fluctuate by roughly 0.3m.
Is this behaviour normal and how can I mitigate the variance?
(Sorry, I asked this question in a previous thread before, but didnt receive any answers).
