"multilateration (MLAT) ... is a technique for determining the position of an unknown point, such as a vehicle, based on measurement of the times of arrival (TOAs) of energy waves traveling between the unknown point and multiple stations at known locations."

This is not the same problem. We don't have the distance to the source, only the difference in arrival times.
