You will be surprised with the accuracy of GPS chipsets of phones... it can be 50-200m off !
Just imagine the effect it can have on a laptime.
That's why I personally laugh when someone tells me his laptime, which was measured with Harry's laptimer on an iphone 
I see from the specs that the accuracy is 5m 95% CEP*.
That's mediocre in my opinion.
I bought this GPS chipset a few months back, the position accuracy is 1.8m (10Hz update frequency). 39.95$ |
i run PBox and Harrys at the same time and have seen differences 0.01 to 0.50s depending on the day and circuit.
