It's in the same place.The 2 one is the Android tablet computer, a mobile phone is HTC G10, also received together in the same position, find that the accuracy is not the same as (the latter 20 meters or so), but also may be about 10 meters position difference.The accuracy of this GPS device can reach 1-2 meters, while the same location in real-time single point positioning error of 10 meters, a reasonable explanation.

Oh the single point positioning accuracy is about 10 meters, but also have a great relationship with the environment around you, if in the city, the accuracy of twenty meters are possible, if the open place, outside. Ten meters should not be a problem.

Can only say that the use of professional measurement RTK will certainly be higher than the navigation accuracy of GPS single point oh
