Universal Receiver Architecture for Blind Navigation with Partially Known Terrestrial and Extraterrestrial Signals of Opportunity

Abstract:	A universal receiver architecture that is capable of exploiting partially known signals of opportunity (SOPs) for navigation is presented. A partially known signal refers to a signal to which only the center frequency and bandwidth are known to the receiver. Assuming that the SOP follows a standard modulation scheme, e.g., phase shift keying (PSK) or quadrature amplitude modulation (QAM), and a standard multiplexing scheme, e.g., code-division multiple access (CDMA) or orthogonal frequency-division multiplexing (OFDM), the proposed receiver architecture can blindly acquire and track the SOP to provide a navigation solution. Experimental results are presented showing the proposed receiver successfully producing meter-level-accurate navigation solutions from different types of terrestrial and space signals: GPS, cellular 4G long-term evolution (LTE) and 5G, and Starlink LEO satellites, under the aforementioned partially known assumption.
