locating the ULB's
Just thinking aloud ...
The navy has said that it indicated twenty-odd locations where the pinger sounds might have come from, minus a few scrapped since.
The navy has also said that it identified two pingers, some distance apart.
Suppose the 20-odd locations mean different locations of the submarine, would the distance between the pingers and the difference between the distances of each pinger to the sub offer a means to locate them?
In other words, suppose a pulse from pinger A at distance sA from the sub is received at time tA, and that of pinger B at distance sB at time tB, would the difference (tA - tB) change as (sA - sB) changes for different locations of the sub?
