llimarinen - And that pico station cannot be synchronized directly with GPS anyway, no way the handset can be. Apologies, but you are incorrect here. SnapTrakc is more than just differential GPS. Whether or not you can synch with a signal depends on what you are trying to get off the signal. (e.g. it is often possible to lock to a carrier long before you can pull meaningful info off the signal, or you can lock to the CDMA chips long before you can get understandable voice off the signal) You are right that I could not find my position with just a GPS signal inside a building without some really sophisticated hardware (which essentially would make some ever improving estimates of what it expected to hear). But in a SnapTrack system the handset is told 99.9% of the info it should expect to receive and thus it is much much easier to lock up and obtain the remaining information (chip timing). Shannon's law in action. As for Lars' argument that "100m or 10m, who cares?". ??? Obviously 10m allows an ambulance to find an accident or heart attack victim much much faster than 100m in any kind of populous area. I'm not sure what else to say in this regard. Clark
