TDoA wireless sync clock

We began to develop a system for tracking objects. We choose which method to use TWR or TDoA. In the first method, it is not entirely clear how the system synchronizes, if we use 2 or more anchors. For the second, everything is clear, I wrote multilateration equations, but where can I get a library for wirelessly synchronizing anchors? Thanks in advance for the answers.

Hi Art_Sh,

Library for wirelessly synchronizing anchors is part of the TDOA Software. Please contact Decawave for more details on TDOA Software.

In case of TWR, Asymmetric double sided TWR method is used to reduce clock and frequency drift errors,
Please refer the Application notes - APS013 and DW1000 user manual for more details

Thanks & Regards,
