if lack someone anchor, EKF also work?

Hi, arnaud:
as likely the thread:
I have developed the system asset track system based on the tdoa mode, but I don't use the EKF, rather than hyperbola location algorithm. so I need everyone tag and near anchor's distance diff, but I find that maybe someone anchor don't work. for example:
we have six anchors, previous anchor is anchor1, but crazyflie2 don't receive the anchor2's packet, so the current anchor change the anchor3, so we get the anchor1 and anchor3 distance diff, rather than anchor1 and anchor2 distance diff, EKF don't care if must anchor1 and anchor2 ? only care the distance diff two anchors ? maybe next frame, anchor2 work normally. so we still get the anchor1 and anchor2's distance diff.
