Q:Verify the accuracy of the GPS device to buy back, the way is to use Android under the'gps state 'software, to test the accuracy of real-time single point positioning.1 with two sets of the same Android Tablet Computer (custom machine, type of bad) in the same position for receiving, find that the accuracy is the same (software, are 1-2 meters), but the position would be poor 10 meters or more. 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.

10 meters.To the world in 2013 a total of four global satellite navigation system, in addition to the United States has been in the mature GPS system and commercial operation, the Beidou system, China the European Galileo system, the Russian GLONASS system are still under construction. "The Galileo satellite navigation project" was first conceived by the 30 satellite GPS network to compete with the United States, the beginning of the design proposed in 2008 formally put into operation, and later postponed to 2014, the entire system is only 4 satellites in orbit (as of 2012), in fact it is mainly used to further verify the relevant design and the working system of the system design, after the official start of Galileo satellite will launch. Formal networking satellites are being prepared. China satellite navigation system management office senior engineer Yang Qiangwen introduction, to 2012, the "system" in orbit satellites are also only verify satellite.
