虽然全球定位系统(GPS)在进入大楼后在精确定位方面往往不再有用，但低能耗信标可能会派上用场。当一个人以前从未访问过一个地方时，在整个建筑中没有信号接收问题的导航是一个室内本地化解决的挑战。使用蓝牙低能量(BLE)信标(iBeacon或Eddystone格式)是实现这一目标的媒介。事实上，不同的面向目的的应用程序可以针对特定建筑环境中任何人的需求进行设计、开发和塑造。这项工作提出了一系列后处理过滤器，以提高估计位置的结果，应用三边测量作为主要和直接的技术来定位建筑物内的人。后来的评估试图提供足够的证据来证明这种室内定位技术的可行性。移动应用程序应该是用户在一栋建筑内导航所需的一切。
While the Global Positioning System (GPS) tends to be not useful anymore in terms of precise localization once one gets into a building, Low Energy beacons might come in handy instead. Navigating free of signal reception problems throughout a building when one has never visited that place before is a challenge tackled with indoors localization. Using Bluetooth Low Energy1 (BLE) beacons (either iBeacon or Eddystone formats) is the medium to accomplish that. Indeed, different purpose oriented applications can be designed, developed and shaped towards the needs of any person in the context of a certain building. This work presents a series of post-processing filters to enhance the outcome of the estimated position applying trilateration as the main and straightforward technique to locate someone within a building. A later evaluation tries to give enough evidence around the feasibility of this indoor localization technique. A mobile app should be everything a user would need to have within a building in order to navigate inside.
