Detecting and Mitigating Attacks on GPS Devices.

Area of Science:

• Navigation and Positioning Systems
• Cybersecurity
• Autonomous Systems

Background:

• Global Positioning System (GPS) is vital for positioning, navigation, and timing (PNT) in modern systems like unmanned aerial systems (UASs) and autonomous vehicles.
• GPS signals are vulnerable to disruptions and cyberattacks, potentially compromising system functionality.
• Existing literature lacks comprehensive reviews specifically on GPS security, often embedding it within broader cybersecurity discussions or focusing on niche topics.

Purpose of the Study:

• To provide a comprehensive treatment of Global Positioning System (GPS) security issues, with a specific emphasis on unmanned aerial systems (UASs).
• To bridge the gap in existing literature by offering a holistic review of GPS security.
• To identify current research gaps and suggest future research directions in GPS security and alternative navigation.

Main Methods:

• Systematic review of existing literature on GPS security threats, detection techniques, and countermeasures.
• Categorization of detection and mitigation approaches, analyzing their respective strengths and weaknesses.
• Comprehensive overview of alternative positioning and navigation techniques for GPS-denied environments.

Main Results:

• Detailed overview of prevalent threats to GPS signals and systems.
• Analysis of state-of-the-art techniques for GPS attack detection and mitigation.
• Evaluation of alternative positioning, navigation, and timing (PNT) solutions in GPS-disrupted scenarios.

Conclusions:

• The study provides a foundational, comprehensive resource for understanding GPS security challenges and solutions.
• Identifies critical areas for future research to enhance the resilience of GPS-dependent systems, particularly UASs.
• Highlights the need for robust detection, mitigation strategies, and reliable alternative PNT methods.
