GNSS-Denied Navigation using Direction of Arrival from Low-Cost Software Defined Radios and Signals of Opportunity

This paper describes a novel navigation system for outdoor navigation in conditions where reliable satellite navigation cannot be assumed. It is build around inexpensive of-the-shelf hardware and could be used with several different signal types, allowing flexibility in usage. The system is currently in a proof-of-concept stage, and this paper shows that there are promising preliminary results.
