Just posting a quick bulletin that comes from users a couple pages back. Many of you have questions about your GPSone chip working overseas. Here's something you all should know. Looking at Qualcomm's page about GpsOne
http://www.qctconnect.com/products/gpsone.html, the chipset is GPS technology only as far as the satellites are concerned. This means it is not WAAS enabled according to their descriptions. The reason for it's accuracy is a kind of WAAS system that relies on cell towers (LBS) rather than advanced programming, seperate systems, manual points of reference etc. A problem with this is that overseas, you don't have GPS. You have EGNOS (European Geostationary Navigation Overlay Service) that works Europes gps system. You also have GLONASS (
GLObal'naya
NAvigatsionnaya
Sputnikovaya
Sistema) that is the Russian version. Also in development is Galileo which is being formed by the European Union, which may replace or supplement EGNOS. So, for GpsOne users that have things setup here in the US, your programming is set for GPS service that may have WAAS for accuracy. All your programs are programmed for that. Some are programmed for your LBS capabilities to get the urban areas that satellites currently don't reach. If you're going overseas, consider getting a program that uses EGNOS or GLONASS instead of GPS with/without WAAS. Those may easily be picked up and the GpsOne chipset since they had a global market in mind (LBS for GSM). If you're relying on Delorme or other programs, you're stuck in the mud.
Also, the chipset supports 4 modes of operation. 3 of these modes involve having towers available for LBS accuracy. Only one is left for standalone sky only service. Nothing is posted describing how this chipset works, but I would assume it is set to automatically determine the best solution for it's fix. This means that if the chip detects towers are available, it will use them. If not, it won't. There may be some software flags that can be sent to the chipset telling it what to do/look for. If I were programmers, I would be for determining what the interface to the chip is. If there is a set of software flags that can enable/disable the LBS modes, this should help in streamlining how the chip starts up and how fast it does it.
Hopefully this helps some and sparks ideas in others.
