TDOA
A geolocation technique that fixes an emitter's position from the tiny differences in the time a signal arrives at three or more spatially separated receivers. Each pair of receivers defines a hyperbola of possible locations, and their intersection gives the position.

Why it matters
TDOA fixes an emitter’s position from tiny differences in signal arrival time across separated receivers; for an operator it is a passive, precise way to geolocate a transmitter without alerting it.
