Latency due to mean position?

Wireless Connectivity Ultra-Wideband

I noticed that there is less latency to find the location of a tag you move when you have a high nominal update rate (10 Hz for example) than with a 1 Hz or 0,1 Hz update rate.
I think that this is because there is a sort of “buffer” and the position which is given is a mean position computed on the five last locations for example.
Is it possible to change this ?
Note : I use the DWM1001 development board.
Thanks :slightly_smiling_face:

Hi Oliver,

yes, there is an internal average of the last 3 positions and that unfortunately cannot be disabled in PANS.

Hi TDK,

Is this documented somewhere? I was under the impression that the averaging happens downstream, e.g. in DRTLS app and the manager web application that runs on the gateway (there are toggles).

Kind Regards
Alex

Hi Alex,

I don’t know if this is documented somewhere.

The internal averaging of 3 samples is hard-coded. The further averaging in DRTLS Android Manager and Web Manager is optional, mainly for demo purpose.
