Bill,

I respect and think that your idea = would work on the surface, but I think you over estimate the ability of a cell = phone GPS receiver to be reliable enough for this kind of = task.

First of all, GPS signals have a = signal to noise ratio that is surprisingly small. Secondly, you really have = to mount a GPS antenna so that it sees the sky.

I realize it is tempting to look at = the high availability of cells phones and see it as a simple solution, but if you = were to start to understand the technical details, I think you may quickly = realize the pit falls of the technology and question its ability to perform as = desired.

My personal opinion is that if that solution were to be tried, it would fail to deliver often enough that it = would loose it’s appeal.

Kevin
