Blind Doppler Tracking and Beacon Detection for Opportunistic Navigation with LEO Satellite Signals

IEEE Aerospace Conference, 2021
A Doppler tracking and beacon detection framework for blind opportunistic navigation (BON) with low Earth orbit (LEO) satellite signals is proposed. The BON framework cognitively deciphers partially known signals of opportunity (SOPs) and exploits them ...
