The effective spoofing detection can prevent GNSS receiver from providing erroneous positioning, velocity and timing information. Most of the available multi-antennas carrier phase double difference-based methods, regardless aiding inertial navigation system (INS), exploit divergence in differences derived direction arrival (DOA) characteristics authentic signal signal. However, traditional met...

This paper develops, implements, and validates a powerful single-antenna carrier-phase-based test to detect Global Navigation Satellite Systems (GNSS) spoofing attacks on ground vehicles equipped with low-cost inertial measurement unit (IMU). Increasingly-automated require precise positioning that is resilient unusual natural or accidental events secure against deliberate attack. paper’s detect...

Mesoporous silica nanoparticles (MSNs) were used as a nano-carrier/amplifier to develop a novel MSN-SERS probe for DNA MTase detection. High sensitivity, good selectivity, and rapid analysis are achieved.
