我建议你阅读以下内容关于两种定位算法Trilateration和NonLinear回归体验的文章： R / GA Tech Blog

I suggest you to read the following article about the experience with two positioning algorithms Trilateration and NonLinear Regression: R/GA Tech Blog

你会发现完整的iOS应用程序在 GitHub

You will find the complete iOS App that implements both algorithms from these guys on GitHub

该应用程序非常有助于理解要求的困难室内导航并进行实验。

The App is very helpful to understand the difficulties of the requirement of the indoor navigation and experiment with it.

另请注意： Apple确实宣布了在WWDC 2014上使用iOS8核心位置框架进行室内定位，但几个月后，他们停止了该计划。这个新功能有很多热潮。 Apple决定只为大公司提供该计划。您可以在此处注册。

Also please note: Apple did announce the indoor positioning on WWDC 2014 with the Core Location Framework in iOS8, but after some couple of month they stopped the program. There were a lot of rush about the new feature. Apple decided than to offer the program only for big companies. You can register for it here.

了解Apple战略非常重要：与iOS8中的核心位置框架室内定位功能相比，iBeacons技术用于接近和广告。第一个只是第二个的补充，而不是替换。

It is important to understand the Apple strategy: The iBeacons technology is for proximity and advertising in contrast to Core Location Framework indoor positioning features in iOS8. The first one is just an addition to the second one, not replacement.

Estimote Blog上还有一篇有趣的文章关于灯塔技术的物理学。。对你有用的部分从句子开始当我们开始构建它时，我们正在尝试一种称为三边测量的方法。

There is also an interesting article on the Estimote Blog about the physics of beacon tech.. The useful part for you begins with the sentence "When we started building it, we were experimenting with a method called trilateration."
