Dear all

what is the max GPS accuracy of an object i can obtain with the Adafruit Ultimate GPS Logger Shield?

These are the specs:

-165 dBm sensitivity, 10 Hz updates, 66 channels

I know that it depends on signal level and #of satellite's that i can reach, my question is:

how much can be accurate my position if i leave the arduino in the same position (even for minutes or hours) and wait for the righe # of satellite's

0-5 cm?
5-10 cm?
10-20 cm?
20-40 cm?
40-80 cm?

Thanks for all in advance
