长期演进（LTE）系统的适当定位特性和快速部署使得该技术成为未来卫星和地面混合场景的有希望的候选者。然而，对可实现的LTE定位能力的进一步研究对于商业或现实的网络部署仍然是必要的。本文描述了一种在LTE网络中提供独立定位的工具。该工具是一个软件定义无线电（SDR）接收器，工作在LTE物理层，执行捕获，跟踪和定位。SDR LTE定位接收器在静态场景中得到验证，在1.08 MHz信号带宽的情况下，在没有多径的情况下，位置误差低于3米。
The appropriate positioning characteristics and fast deployment of Long Term Evolution (LTE) systems makes this technology a promising candidate towards future satellite and terrestrial hybrid scenario. Nevertheless, further studies on the achievable LTE positioning capabilities are still necessary for commercial or realistic network deployments. This paper describes a tool that provides standalone localization in LTE networks. The tool is a software-defined radio (SDR) receiver working at the LTE physical layer, performing acquisition, tracking and positioning. The SDR LTE positioning receiver is validated in a static scenario, showing position errors below three meters in the absence of multipath for a signal bandwidth of 1.08 MHz.
