Hi,arnaud:

(1) Channel 2 and 5 can reach about 70m, why the Decawave porvide the range about 290m?
(2) yes, I also don't find the UWB PA, so we will add more anchors to cover whloe area.

hi, arnaud: I have understanded their method, so cool. I think the key point is the piture: 1.png About clock skew: so the anchor 0 transmit timespan, we can set as constant 1ms, so 2.png =1ms; then other anchors or robot record the received time, so we calculate the clock relative skew to anchor 0,...

Hi, all:

I have tested the dwm1000 range distance, only about 70 meter? the office display about 290 meter, I need add some PA?
or how to do we can add the range?

hi,

Thank you very much!
I will research and try it.

hi，
the anchor would send data and the tag would only receive? the way have related paper ?

Hi,everyone:

Now a tag with muti-anchor, but I want to add more tag mount on aircraft with multi-anchors, what method to achieve it?
Thanks!

Hi, see the lps-code-firmware, find that calculate the distacne node is tag, we want anchor to do the thing. so we change code, when tag receive answer, packet the poll_tx, answer_rx and the final_tx to send to anchor, but the issue is final_tx wiht tag, I must get timestamp before transmit final, h...

Hi,everyone:

I try the dwm1000 mount at crazyflie2.0, test the airtime? the picture as follow: the y axis mean? the unit is ms? so the airtime is about 2~4ms?

Hi,

Wow, Thanks! I appreciate it!
But why Alpha plus Beta = 2 ?

Hi,arnaud:

Thank you for your reply!

another question, I find every dwm1000 module maybe the antenna delay is different. if we set the same delay, the measure error will more high.
can we dynamicly correct the every module?
