GPS World Magazine Features ASPIN Laboratory Research in UAV and Ground Vehicle Navigation with Cellular Signals of Opportunity

The cover of the April issue of GPS World magazine featured an article by Prof. Zak KassasJoshua MoralesKimia Shamaei, and Joe Khalifeentitled “LTE Steers UAV.” The article discusses how cellular CDMA and LTE signals could be exploited for navigation and presents a specialized navigation software-defined receiver (SDR) called MATRIX developed at the  ASPIN Laboratory. The article shows simulation and experimental results of ground vehicles and unmanned aerial vehicles (UAVs) navigating exclusively with cellular CDMA and LTE signals via the MATRIX SDR. Moreover, the article presents a radio simultaneous localization and mapping (SLAM) approach for autonomous vehicle navigation via a tightly-coupled cellular-aided inertial navigation system (INS) framework, achieving GPS-like performance in the absence of GPS signals.
