Wow! some of the distances from detectors to strike location are thousands of km. Now I am curious how it works. my guess is some sort of low frequency radio detector(long antenna?) and a good(gps disciplined?) timer. As the station integrator gets the reports it solves for what point could of generated this collection of time stamps.
Update: found the info page. It took me longer than it should have, but in my defense it was under the heading "cover your area"
You don't need a particularly good antenna to receive lightning strikes. At night, I can hear a thunderstorm almost anywhere in the midwest US just by turning on an any old AM radio.
But yeah, timing is critical to get an actual location.

And here is a paper on the method used to integrate the reports.
