黑莓GPS测试演示 [英] Blackberry GPS Test Demo

问题描述

能否请你帮我创造黑莓GPS样品展示？其实我搞砸与黑莓的许多设备和某些具有GPS接收器和其他人没有。

Can you please help me to create Blackberry GPS Sample Demo? Actually I am messed with so many devices of Blackberry and some has GPS receiver and others don't have.

如果设备有GPS接收器将如何搜索当前设备的位置？如果设备没有什么的GPS像BB 8520？

If the device has GPS receiver how it will search for the current device location? and what if the device does not have GPS like BB 8520 ?

请分享你的理解有关GPS的黑莓和我怎么能实现设备位置的纬度和经度无论是通过GPS或没有。

Please share your understandings about GPS in Blackberry and how can I achieve Latitude and Longitude of Device Location whether by GPS or not.

感谢您

推荐答案

<一个href=\"http://stackoverflow.com/questions/8711230/how-i-can-get-latitude-and-longitude-of-current-location-in-blackberry\">This previous SO后应该指向你在正确的方向。

This previous SO post should point you in the right direction.

对于其他的方法，你可以使用三角，在其中您可以从使用​​的信号强度至少3个信号发射塔，以获得您的位置的粗略估计。这取决于你如何准确需要的位置，三角将最有可能会比GPS快，但GPS会显著更加精确（三角往往有100m左右的误差最好的情况保证金）。

Regarding other methods, you can use Triangulation, in which you can use the signal strength from at least 3 cell towers to obtain a rough estimate of your location. Depending on how accurate you need the location, Triangulation will most likely be faster than GPS, but GPS will be significantly much more accurate (triangulation tends to have a best case margin of error of about 100m).

不过请注意，如果你是在建筑物内或不具备的天空一个明确的说法，该GPS将最有可能无法正常工作。

Note however, that if you are inside a building or do not have a clear view of the sky, the GPS will most likely not work.
