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...

Phase effect on the modal interaction of flow instabilities is investigated for laminar-to-turbulent transition in a flat-plate boundary-layer flow. Primary and secondary three-dimensional (3-D) oblique waves at various initial phase differences between these two instability modes. Three numerical methods are used systematic approach entire process, i.e. before onset well into fully turbulent F...
