Master Thesis for “Development and Evaluation of AI-based GNSS Spoofing Detection Methods for Railway Applications”
Responsibilities
Literature review of classical methods to detect Spoofing at different levels within GNSS receiver processing chain.
Literature review of suitable AI based methods to detect Spoofing.
Creation of a set of “synthetically” generated GNSS authentic and overlayed Spoofing signals with a GNSS Simulator.
Investigation of the Spoofing effect on the GNSS receiver (Software receiver) output level (Observation of the output signals at different stages, PVT level, Post-correlation level, Pre-correlation level).
Implementation of 2 or 3 suitable AI based Spoofing detection algorithms with an adapted set of configuration parameters and train the algorithms based on the synthetically generated data set with and without Spoofing.
Evaluation of the detection performance of each individual method in terms of detection probability for a given false alarm rate.
Apply the most suitable method/s on real signal with overlayed spoofing signals obtained from a train measurement Campaign.
Compare the detection performance based on real-world signals with the detection performance based on synthetically generated data.
Evaluate the results and give recommendations for further improvements / tuning of AI based Spoofing Methods.
