DWM 1001 anchor placement

[Yves_Bernard_Qorvo]

Hi Cristoph,

It will help to put them a different high, but the best way to improve Z accuracyis to increase the distance between anchors on the Z axis.

The poor Z accuracy is due to the high GDOP due to proximity of anchors along the Z axis. Maybe have a look at the last post from :

Location Accuracy of Decawave Modules

Hello gumush, The location given by gateway is in 3D and in the below format , if you use ‘lep’ command. b’POS,21.72,65.28,2.76,92\r\n’ Where x=21.72 , y=65.28, z=2.76 with a confidence rate of 92% May be but in my experience Z axis values do not make any sense when deployed. The issue with the z axis is that normally your GDOP (Geometric dilution of precision) is terrible in that direction. GDOP (or HDOP/VDOP (horizontal/vertical DOP)) is a term commonly used in GPS, it’s a measure o…
