我想我看过的地方，Android的全球定位系统的精确度约为10cm？

I thought I have read somewhere that the accuracy of Android's GPS is about 10cm?

任何人能证实或纠正呢？原因是，我的申请，我试图发展保持位置的用户访问跟踪，这将帮助我极大知道错误的保证金，我可以期待什么？

Can anyone verify or correct this? Reason being is that my application I am trying to develop keeps track of locations an user has visited and it would help me out tremendously to know the margin of error I can expect?

推荐答案

10厘米？没有机会。在任何情况下，Android是只是一个设备操作系统; GPS设备的实际精度取决于该设备的芯片组。 Android的可能的理论上的能够与精度水平包容的设备，但仅此而已。

10 centimeters? No chance. In any event, Android is just a device OS; the actual accuracy of a GPS device is dependent on the device's chipset. Android may be theoretically capable of accomodating devices with that level of accuracy, but that's it.

GPS设备的精度通常不是psented作为一个简单的距离$ P $，反正。通常，设备的精度被给定为随着测量是从真位置距离之内，该百分比的距离。一个典型的精度手持GPS设备会像你的尺寸的30％，不到50米的真实位置（是的，这些设备通常的是的不准确）。

The accuracy of GPS devices is normally not presented as a simple distance, anyway. Usually, a device's accuracy is given as a distance along with the percentage of measurements that are within that distance from the true location. A typical accuracy for a hand-held GPS device would be something like 30% of your measurements within 50 meters of the true position (yes, the devices are typically that inaccurate).
