Software-Defined Radio LTE Positioning Receiver Towards Future Hybrid Localization Systems

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.
