[Electronics-talk] GPS in the Big City

[Christopher Chaltain]

I'm not sure about the BrailleNote running Sendero, but iPhone/Android 
running a GPS app will also use cell tower and wifi hotspot 
triangulation to improve location reliability. I would think this would 
help quite a bit in a large metropolitan area, but I can't speak from 
experience.
