Hi Liam,

Do you have more details regarding your setup ?

Thank you,

Hi Liam,

could you also say which kit/system you are using or if you have own HW?

Hi,

I recently started using Decawave UWB kit.

As a simple test of accuracy, when I repeatedly read the location for a static tag, it fluctuations a lot and the error sometimes goes beyond 50 cms.

JFYI, I have accurately measured the anchor positions manually and configured them.

I am using MDEK1001 (connected to raspberry through USB) and calling dwm_pos_get to get location info.

Any pointer to understand this behavior and possible accuracy improvement suggestions would be highly appreciated.

Regards,
Ram
