Personal-Privacy-Device-Interference-in-the-WAAS. - The Federal Aviation Administration (FAA) Wide Area Augmentation System (WAAS) Monitoring Team has investigated increases in Radio Frequency Interference (RFI) events observed since 2009. The Oklahoma City-based WAAS Monitoring Team initially observed in-creased RFI events at certain WAAS Reference Stations (WRSs). The major source for this increase in RFI events has been attributed to Global Positioning System (GPS) maskers used in motor vehicles for personal privacy. The use of these Personal Privacy Devices (PPDs) is observed in WRS operation via a response in the Automatic Gain Control (AGC) and the signal to noise ratio (C/N0) report-ed by the reference receivers.,2012-10-10 15:08:38,下载3次
GNSS-Spoofing-Detection-based-on-Receiver-CNR-Est - A perceived emerging threat to GNSS receivers is posed
by a standoff spoofing transmitter that emulates authentic
signals but with randomized code phase and Doppler over
a target area extending over several hundred meters in
radius. The victim GNSS receiver computes the
navigation solution based on these counterfeit signals
which are subsequently passed on to the location services
application layer as being reliable with potentially
damaging consequences.,2012-10-10 15:07:36,下载7次
Real-Time-Spoofing-Detection-Using-Correlation-Be - A real-time method for detecting GPS spoofing in a narrowbandwidth
civilian GPS receiver has been implemented and
tested, both in the absence of and in the presence of
spoofing.,2012-10-10 15:05:13,下载6次
Pre-and-Post-Correlation-GNSS-Interference-Detect - The design of the detection device is based on software defined radio (SDR) technology. A real-time software GNSS receiver enables the continuous monitoring of various metrics of the receiver processing and therefore robust detection of the appearance of interference.,2012-10-10 15:03:52,下载13次
