Maybe I'm an ass for pointing this out, but it's trilateration, not triangulation. I set out to learn the mathematical concept, and not knowing the right term had me waste an entire evening looking at something more closely related to tessellation, than spatial position locating.
You don't sound like an ass at all. Hell, if I had wasted the better part of an evening due to a simple nomenclature mix-up, I'd post it as well when the right concept comes up. It might save others some time.
Funny thing is I'm really familiar with the tech - I did COIN in the bush war in Angola, where we did a lot of triangulation (old school, using an oscilloscope). I've given up trying to explain the difference.
