the electromagnetic pulse be~
tween two stations will Fe uscd to determine a bkyypertolic curve which
runc through ground moro.
The point cf intereection of two or mere eurves
determines ground zero.
There are two syetems,.
One of the systems ie known as the long
vase line system and the other, the short base line system,
has two sets of stations,
The long bese line has one

North Carolina.
The shert ba se lines have one set of stations located in
