Research Topic Description, including Problem Statement:

Global Navigation Satellite System (GNSS) anomaly detection can normally only be done using dedicated expensive hardware. Modern GNSS receiver hardware is able to cope with multiple GNSS constellations and has improvements in RF performance that help reject interference to some extent. There is a significant vulnerability to cyberattack because of the growing ubiquitous use of consumer grade hardware in critical systems. This research will investigate whether simple machine learning (ML) algorithms can be used to detect anomalous GNSS signals by modeling the behavior of consumer-grade GNSS hardware when under duress from rogue signals. The outcome should be a low-cost sensor, based on consumer-grade hardware, for detecting anomalous GNSS that can be widely deployed for protective security.

Example Approaches:

Behavioral modeling of the status and the output of consumer-grade GNSS receiver hardware to detect the circumstances of divergence from expected conditions.

Relevance to the Intelligence Community:

The Intelligence Community has a growing interest in low-cost wireless and environmental sensing devices that can be used as a convenient platform and infrastructure for protective environmental surveillance, without additional significant costs. GNSS sensing could be added to our designs.
