Positioning or localization is important in many different applications. A robot's location on a dangerous zone, a shopper's location in a store, a package's location in a warehouse and a doctor's location in a hospital are all valuable pieces of information based on which indoor location based services (LBS) can be built. EKOOR makes hardware and software for solar-powered nodes that communicate using the Bluetooth Low Energy (BLE) protocol. These nodes can communicate with smartphones and help the smartphone to be positioned. This project will involve designing an inexpensive, accurate indoor positioning system that uses off-the-shelf hardware and mobile phone platforms. Such a positioning system will enable EKOOR to extend its current indoor LBS platform to provide better indoor positioning and tracking for people and devices in shopping malls, retailers, airports, arenas and museums. Indoor positioning systems have existed for several years. Most existing systems estimate distances between nodes from signal strengths of received messages. Other techniques need specialized hardware. Existing systems typically provide positioning errors over 1 meter. This project will investigate the use of angles of arrival (AoA) of messages to improve positioning accuracy and reduce the error to less than 1 meter in indoor environments. My lab has developed accurate positioning algorithms that make use of estimated distances between nodes. Although our past work has not utilized AoA information, the framework developed in our algorithms will allow for this information to be handled easily. A lot of BLE hardware has entered the market in the last two years because of its anticipated importance in commercial applications. This project is relevant and important in extending the utility of this new technology in indoor positioning.

定位或定位在许多不同的应用中是重要的。机器人在危险区域的位置、购物者在商店中的位置、包裹在仓库中的位置以及医生在医院中的位置都是有价值的信息，基于这些信息可以构建室内基于位置的服务（LBS）。EKOOR为使用蓝牙低功耗（BLE）协议进行通信的太阳能节点提供硬件和软件。这些节点可以与智能手机通信，并帮助智能手机定位。该项目将涉及设计一个廉价，准确的室内定位系统，使用现成的硬件和移动的电话平台。这样的定位系统将使EKOOR能够扩展其现有的室内LBS平台，为购物中心、零售商、机场、体育场和博物馆的人员和设备提供更好的室内定位和跟踪。 室内定位系统已经存在了几年。大多数现有的系统从接收到的消息的信号强度估计节点之间的距离。其他技术需要专门的硬件。现有系统通常提供超过1米的定位误差。该项目将研究如何使用信息的到达角（AoA）来提高定位精度，并将室内环境中的误差减少到1米以下。我的实验室开发了精确的定位算法，利用节点之间的估计距离。虽然我们过去的工作没有利用AoA信息，我们的算法开发的框架将允许这些信息被轻松处理。 在过去的两年里，许多BLE硬件已经进入市场，因为它在商业应用中的预期重要性。该项目是相关的和重要的，在扩大这种新技术在室内定位的效用。
