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…
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…
A Reduced Complexity Cross-correlation Interference Mitigation Technique on a Real-time Software-defined Radio GPS L1 Receiver
Erick Schmidt, Zach A. Ruble, David Akopian +1
The U.S. global position system (GPS) is one of the existing global navigation satellite systems (GNSS) that provides position and time information for users in civil, commercial a…
A Performance Study of a Fast-Rate WLAN Fingerprint Measurement Collection Method
Erick Schmidt, Misbahuddin A. Mohammed, David Akopian
Indoor positioning systems exploiting WLAN signal measurements such as Received Signal Strength (RSS) are gaining popularity due to high accuracy of the results. Sets of RSS and ot…
