Rejection of Smooth GPS Time Synchronization Attacks via Sparse Techniques
Erick Schmidt, Junhwan Lee, Nikolaos Gatsis +1
This paper presents a novel time synchronization attack (TSA) model for the Global Positioning System (GPS) based on clock data behavior changes in a higher-order derivative domain…
A GPS spoofing detection and classification correlator-based technique using the LASSO
Erick Schmidt, Nikolaos Gatsis, David Akopian
This work proposes a global navigation satellite system (GNSS) spoofing detection and classification technique for single antenna receivers. We formulate an optimization problem at…
Indoor positioning system using WLAN channel estimates as fingerprints for mobile devices
Erick Schmidt, David Akopian
With the growing integration of location based services (LBS) such as GPS in mobile devices, indoor position systems (IPS) have become an important role for research. There are sev…
A Fast-rate WLAN Measurement Tool for Improved Miss-rate in Indoor Navigation
Erick Schmidt, David Akopian
Recently, location-based services (LBS) have steered attention to indoor positioning systems (IPS). WLAN-based IPSs relying on received signal strength (RSS) measurements such as f…
Fast prototyping of an SDR WLAN 802.11b receiver for an indoor positioning system
Erick Schmidt, David Akopian
Indoor positioning systems (IPS) are emerging technologies due to an increasing popularity and demand in location based service (LBS). Because traditional positioning systems such…
Exploiting Acceleration Features of LabVIEW platform for Real-Time GNSS Software Receiver Optimization
Erick Schmidt, David Akopian
This paper presents the new generation of LabVIEW-based GPS receiver testbed that is based on National Instruments' (NI) LabVIEW (LV) platform in conjunction to C/C++ dynamic link…
