It's actually trilateration or whatever the equivalent is on a 3d plane.
The 3D equivalent is quadrilateration (or multilateration). I would love if CCP made more attempt to clarify that the scanning system does not use triangulation.

In the case of GPS, it's much simpler : the entire system (satellites, receivers) are time-synchronized, and the satellites continuously broadcast their local time alongside their ID (that's the simplified version, actual broadcast signal is a bit more complicated, including a lot of other data too once in a while at least), so when the receiver picks up the signal from any satellite, it can easily tell just how far out the satellite is by simply comparing the local time with the signal received. And since you KNOW where the satellites are (their orbits are known with a fairly high degree of accuracy), then you can do this type of location-guessing.
But with probes... you can not possibly detect the DISTANCE from a signal, not unless you know the exact time the signal was sent. So when you're "searching for anomalies", distance from it is the last thing you should be able to determine, not the first.
You get distance by sending out a signal and when it reflects you measure the distance from it to you using the time difference.

surley if it needs 4 signals, its quadrangulation?
// gets coat.
No, for that you need angles. Scan probes give you distance only.

I beleive Triangulation is correct scientific term. It dates back to when sailors navigated the seas via the stars, the only difference is that in space there is a 3;rd dimension.
So anyone who beleives that triangulation means 3, is merly showing their ignorance.
First, triangulation is not the correct term for what we're doing in EVE. What we're doing is quadrilateration, finding where 4 spheres intersect in 3D space. In EVE's case, I believe the closer that intersection is to your target signature the higher the signal strength.
Second, triangulation has two key parts: three and angle. If you believe triangulation means anything other than using three angles to find a location then you're merely showing your ignorance. Note that probes in EVE merely give you distance, not direction, which is why EVE does not use quadrangulation.
