FGI's GNSS Spoofing Dataset Repository (FGI-SpoofRepo)

FGI's GNSS Spoofing Dataset Repository (FGI-SpoofRepo)

Description

This repository houses a new collection of raw In-phase and Quadrature (I/Q) data comprising live recordings of GPS L1 C/A, Galileo E1, GPS L5, and Galileo E5a signals. These datasets cover three distinct types of spoofing characteristics (synchronous, asynchronous, and meaconing), making them valuable examples for testing the effectiveness of various anti-spoofing techniques, whether for detection or mitigation purposes. The inclusion of live signals in multiple GNSS frequencies and the presence of cryptographic signatures in Galileo E1 signal make these datasets potential benchmarks for assessing the resilience performance of multi-frequency multi-constellation receivers. The true receiver is stationary in all four scenarios. Its position estimated by a geodetic-grade receiver is 60.182°N, 24.828°E with an altitude of 47.248 m. The repository contains several folders, each of which represents a different scenario. The main folder "FGI-SpoofRepo" following sub-folders: - TG_SFMC (Targeted Single Frequency Multi Constellation) - TG_DFMC (Targeted Dual Frequency Multi Constellation) - UT_DFMC (Untargeted Dual Frequency Multi Constellation) - Meaconing_DFMC (Meaconing Dual Frequency Multi Constellation) - Example_scripts (Example scripts to replay the datasets) Summary of spoofing datasets can be found below: Name Duration (s) Spoofing Signal(s) Targeted SFMC 370 L1, E1 Targeted DFMC 370 L1, E1, L5, E5a Untargeted DFMC 370 L1, E1, L5, E5a Meaconing DFMC 470 L1, E1, L5, E5a RF Recording Device: The raw I/Q data samples are captured using the stereo dual-band GNSS front-end developed by Nottingham Scientific Limited (NSL). RF recording configuration of the front-end can be found below: Parameters Frequency Bands (L1/E1) Frequency Bands (L5/E5a) Center frequency (MHz) 1569.03 1176.45 Sampling rate (MHz) 26 26 Data type Real Complex Sample bit width 8 bit (I) 8 bit + 8 bit (I + Q) Bandwidth (MHz) 4.2 10.09
