Aymen_Bimani Posted July 1, 2015 Share Posted July 1, 2015 Hi all,, I'm asking how the the range for GPS 64s accuracy by meters? I spent a lot of time to search for the accuracy but I didn't get any useful results.! Your cooperation is highly appreciated Regards Aymen Quote Link to comment
Pacific NW Posted July 4, 2015 Share Posted July 4, 2015 Using GPS + GLONASS mode, and with WAAS turned off, I typically see 3m (9 ft.) EPE "accuracy". Not sure if that is the info you are looking for. Quote Link to comment
+BikeBill Posted July 6, 2015 Share Posted July 6, 2015 I get 3m/9ft like Pacific NW but with WAAS on. This is out in the open, of course, not back in the woods. Quote Link to comment
+Red90 Posted July 6, 2015 Share Posted July 6, 2015 As good as any other consumer, non corrected GPS. Regardless of what the unit states, the best you get with a clear view of the sky in a WAAS serviced area is 4 meters without WAAS and 2.5 meters with WAAS. Less with any obsructions, reflections, bad satellite pattern and so on. Quote Link to comment

Not sure if that is the info you are looking for. From this reference: http://www.interpine.co.nz/news/Lists/Posts/Post.aspx?ID=96 "If the GPS displays an Accuracy of 10m, does this mean it is 10m from the actual / absolute location? MOST DEFINITELY NOT !! Firstly it is a measure of precision and in no way indicates accuracy. GPS's display to the user an estimate of position error (EPE)....." Or, EPE is not a measure of accuracy, but a measure of precision. However, as the article continues, the manufacturers do not provide a qualitative value of the percentage of readings that are within the displayed values of EPE. Regarding the definitions of precision and accuracy, I accept those from here: https://en.wikipedia.org/wiki/Accuracy_and_precision Edited July 6, 2015 by Team CowboyPapa Quote Link to comment
