Detection and Localization of GPS Interference Source Based on Clock Signatures

Detection and Localization of GPS Interference Source Based on Clock Signatures. Smith, J. B., Wood, J. M., Martin, S. M., & Brashar, C. In pages 3528–3540, September, 2022.

Paper doi abstract bibtex

This paper focuses on the development and testing of spoofing detection and localization techniques that rely only on clock deviations to identify threat signals. Detection methods that rely on dynamic receiver geometries to triangulate threat locations or signal geometry to identify spoofing are not considered here. Instead, this paper focuses on single antenna receivers and assumes the receiver tracks only the inauthentic signal. The quality of the receiver clock has a significant impact on the performance of the receiver tracking loops. Low quality clocks have frequency instabilities that inherently limit the sensitivity of the receiver to slow growing errors. Some clocks provide better frequency stabilities but have a higher white frequency noise that can induce false detections. Because of these trends, various detection methods are tested with four types of receiver and transmitter clocks of varying quality.
