position

[Auer, Karl James]

Um - if (and I think it's a BIG if) the signal strengths are linearly indicative of distance, then basic trigonometry does the trick. I don't think it's that simple, though. The attitude of the aerial is probably pretty important too, and the nature of any obstructions also.

Regards, K.
