Feasibility of CSAC-Assisted GNSS Receiver Fingerprinting
International Association of Geodesy Symposia, 2023 AbstractInterference and jamming of Global Navigation Satellite System (GNSS) signals can induce inaccurate Position, Velocity and Time (PVT) information, resulting in crucial integrity and even security issues. The poor stability and accuracy of the GNSS receivers’ internal clocks, i.e.
