Will Ezbuilder see and use a gps that is connected to the usb port of your notebook attached to your robot ? I have one left over from microsoft's streets and maps.
So, in simple terms, yes probably. Try it and see

sorry. Feel free to erase it. But, if you want to answer the question, I would apreciate it.
Thanks for letting me know.

Short answer is that you will need to use the GPS EZ-Script commands to make it work. GPS accuracy is pretty terrible
Most modern standalone GPS devices now have WAAS assistance data, but need a clear view of the southern sky and the data is better near major airports and population centers (the data is received by the GPS from a geostationary satellite, but is provided by ground stations at airports, and the further you are from the airport, the worse the data is
WAAS accuracy with a clear view of the sky and visibility towards the southern horizon is under 2 meters.
If you are near a coast or navigable river, investing in a DGPS receiver (attaches to your GPS external antennae port may be a worthwhile investment. It provides similar accuracy to WAAS when in motion, and if stationary you can get live accuracy down to under 1/3 meter and with post processing down to 1-2 centimeters (although post processing is too slow for any robotics application).
Without and of these corrections, accuracy is between 2 and 15 meters, but generally closer to 2-3 with a clear view of the sky and at least one horizon for the (the further apart the satellites you are using for a fix are from each other, the better the accuracy, and you get the best altitude accuracy from birds near the horizon)
I won't get into the new Class III satellites or military devices which make use of a second signal on a different frequency since there really aren't any class III receivers available yet, and not enough birds up to make it useable, but in a few years, we'll have sub-meter accuracy on consumer grade devices standard.
All that being said, if the device @Moviemaker is asking about is the one I suspect it is, I would expect 2-15 meter accuracy from it as it has none of the corrective features I mentioned.
