You haven't defined "indoors". I think you will have to try it in your location(s). It won't work deep inside a machine room. We tried it once in a typical two-story silicon valley office building. It didn't work there. We also tried it in the 5th floor of a modern office building with a great view. It didn't work, probably because of some anti-heat coating on the windows. Inside my single floor house, they work most of the time. [email protected] said: > I don't think GPS is ever so in accurate as to have a 1 second error.

I don't have examples handy but I wouldn't depend on a single/quick answer in any critical application. -- These are my opinions.
