What is Cellular OFDM Signals for Navigation about?

This article introduces a novel receiver that utilizes downlink OFDM-based cellular signals for navigation in GPS-denied environments, achieving meter-level accuracy. The receiver simultaneously exploits signals from multiple logical antenna ports, significantly enhancing sensitivity and tracking performance, demonstrated through experimental results in a GPS-jammed setting. The proposed design outperforms previous state-of-the-art receivers, achieving a 2-D position RMSE of 2.6 m over a 5 km trajectory.
