The device allows for *precision* down to a fraction of an arc-second. minute. In terms of *accuracy,* I doubt it will be better than 1 meter. Longitude and latitude to ten arc_minutes were all that was required for my application.

It's simple to use and works well with the Raspberry Pi. When I'm 5 feet away from a window in my one-story house, it gets fixed without too much trouble. It outperforms an AdaFruit unit that costs more.
Startups that come after you get a fix faster. br>It should be quicker to fix things outside, but I haven't tried it yet.
I bought two of these; the first had some issues, such as not being able to power it via pinouts, but the second worked fine on the breadboard, and the speed and accuracy were sufficient for my needs.
Our proposal benefits from the accuracy and speed with which we can obtain a position.
