PDoA in three dimensional space

Hi all,

we have a Beta PDoA kit with 2x DWM1002 nodes and 2x DWM1003 tags.
It works fine for two-dimensional localization, but (like it is written in the documentation) as soon as both antennas have different heights, we get kind of useless results.
In the documentation it is written, that more complex antenna arrays are required therefore and Decawave is working on that.
Is there any outcome yet?
Or what is the easiest way, to get spatial awareness in the three-dimensional space?

Thanks in advance,
