Antenna delay calibration question

Hello,
I’ve used aps014 algo to calibrate antenna delays in system of 3 anchors and it works pretty well. Now I’d like to add tag to this system, could someone tell me if it is possible to use this optimization algo in situation when I have some sort of tags that could work in many systems at the same time. Maybe it is better to calculate delay in other way?

If someone meet such a problem I would be thankful for any idea.
