Dear All,

May I know what are the improvements for TDoA V2 as compared to TDoA V1?

What is the position accuracy for V2 version?

Thanks!
Sam

Hi,

The main improvement is in adding extra data in the packet to increase the chance of getting good measurement. We have added packet sequence number and anchor distances in the packet, that way the receiving algorithm only needs 2 packets to calculate TDoA and this makes the algorithm more resilient to packet loss.

Once we have ironed-out all the bugs, the precision accuracy should be improved in the sense that we will get more data in the kalman filter and less outliers.

hi, arnaud:

I want to know more about TDoA V2 method. , or how much time to release it?

Hi Justin, you can look at this weeks blog post .
