This repository contains a collection of raw In-phase and Quadrature (I/Q) GNSS data samples that were recorded during a jammer test campaign named ‘Jammer Test 2023’. This test campaign was hosted in Norway. The digitized I/Q data samples were captured via a record and replay device called ‘LabSat 3 wideband’. It comprises of live recordings of GPS L1 C/A, Galileo E1 signals. These datasets contain one high power jamming and two other distinct spoofing scenarios (i.e., incoherent and coherent), making them valuable examples for testing the effectiveness of various anomaly detection/mitigation techniques in real world scenarios. The repository contains several folders, each of which represents a different scenario. The main folder "JammerTest2023" has the following sub-folders: - JT23_4.1.5 (Jamming) - JT23_16.1.1 (Incoherent spoofing) - JT23_17.6.1 (Coherent spoofing) Summary of spoofing datasets can be found below: Name Scenario Description Duration (s) Spoofing Signal(s) JT23_4.1.5 Continuous high powered pseudo-random noise jamming 1174 L1, E1 JT23_16.1.1 Incoherent spoofing using broadcast (true) ephemerides 896 L1, E1 JT23_17.1.6 Coherent spoofing using broadcast (true) ephemerides 400 L1, E1 RF Recording Device: The raw I/Q data samples are captured using the the Labsat wideband 3 record and reply device. RF recording configuration of the front-end can be found below: Parameters Frequency Bands (L1/E1) Center frequency (MHz) 1575.42 Sampling rate (MHz) 30.69 Data type Complex Sample bit width 16 bit (I+Q) Bandwidth (MHz) 30
