Hmmm. If you order the sensors from first received to last received (let's say A, B, and C) then you know the DIFFERENCE in distance between A B and C. You don't however yet know any distances. Ie:

'a' is the distance between object and A
'b' is the distance between object and B
'c' is the distance between object and C

∆AB is the time difference between A and B reception

so, b=a+(344*∆AB)

This means that distance 'b' is distance 'a' plus 344 times the time difference (assuming time is in seconds).

You could make a whole lot of those equations, but I don't think they could ever tell you a concrete distance, just a bunch of relations.

Does anyone think otherwise?
This is as far as I've gotten. Im pretty much stuck here.
