[QUOTE="pretzel_man, post: 658307, member: 927"] Hello Charley.... Here is my understanding, and maybe someone from Corporate or the DIAD group and clarify if I'm wrong. There are two GPS receivers. One in the vehicle (telematics), and one in the DIAD. In general (by default), the DIAD records a GPS reading at specified places. At a scan, at a signature, and at a stop complete. It does look at Dilution of Precision reading and tags the record accordingly. Also, the DIAD sends up a GPS reading if it has not made a stop for some time (14 minutes I think) Finally, at the DIAD end there is a parameter that can be changed to have the DIAD record and store GPS reading each second. That can be played back in DPS Then there is the vehicle Telematics side. It also has a GPS receiver and an external antenna. It is [U]constantly[/U] gathering GPS readings (including all parameters). At the end of the day, it sends the data to a big database in the sky. Both sources DIAD and Telematics can be plotted on a map, including Google Earth or Microsoft Live. The information is very powerful. It points out management dispatch problems as well as driver problems. Of course GPS is not 100% accurate. From what I've seen, Telematics is more accurate than the DIAD. Probably because it has an outside antenna. Both are remarkably good however. Did that answer your question? P-Man [/QUOTE]
