[QUOTE="cosmo1, post: 1021154, member: 13442"] I'd have to call my son to be sure (he used to be a cell phone tech), but devices like cell phones and the DIAD use a combination of GPS signals from satellites and triangulated signals from cell towers to determine position. Depending on the sensitivity and accuracy of the gps antenna in the device (ever had the DIAD go crazy for a while after dropping it?), the triangulation method may be more accurate. If the antenna is sensitive enough to pick up a sufficient number of satellites, the gps method will be more accurate. In other words, it's just as accurate as the signal it gets. [/QUOTE]
