Re: Verizon Fascinate GPS Inaccurate?

I just spent a little time playing with GPS Test, and the results were better than I'd have guessed.

I was able to see 10-12 satellites and lock on immediately with no problem. The first 4 or 5 locked in less than 5 seconds and the rest within 20-30 seconds. The locks seemed to come and go, dropping as low as four locks out of six available satellites at one point.

According to GPS Test, the accuracy was anywhere from 5-50 feet, which I think may be a little generous. I was sitting at least 40 feet from where Google Maps placed me, 25 feet from the spot on the Bing map, and a good 200 feet from where Verizon Navigator spotted me. (Navigator gave me an address, not an exact spot.)

That's a very different result from what I used to get on my Touch Pro, where Navigator was usually spot on accurate and Google was 10-15 feet off. But, the Fascinate is much faster finding satellites and locking in.

I was testing from the roof of a high-rise, so I'm not sure if that would hurt or help the test. There aren't any other buildings around to block things, but much of the southern sky was obscured by part of the building. I always got accurate results up there for the Touch Pro, so I'd think this would be the same.

I was amused to see that it kept changing my altitude, even though I wasn't moving. The building is around 400 feet high, and it reported me anywhere from 340 to 395 feet up. I'd guess I was somewhere in that range, probably around 375 feet, so it was pretty close.
