Perhaps, I don't know.

I'm trying to measures RF time-of-flight up to a few mm accuracy ( 10mm would be fine, 1 mm would be
fantastic). Well, because I have no influence on the transmitter, I actually want to measure
Time-Differences-Of-Arrival at several receivers.

What do you (or anybody else) think?
