Hacking GPS Book

Learn GPS hacking: how GPS works, common vulnerabilities, testing methods, and ways to secure GPS systems - practical, ethical, lab-ready guide.

Quick intro ​

Explore the fascinating world of GPS hacking with this practical guide. You’ll learn how GPS systems work, where they’re weak, and which techniques people use to test and protect GPS devices and services. This is a hands-on, safety-first overview for students, researchers, and security pros.

What you’ll learn ​

• How GPS systems actually work: satellites, receivers, and signals.
• Common vulnerabilities like spoofing and jamming.
• Practical testing methods and tools used to analyze GPS behavior.
• Defensive measures and best practices to secure GPS systems.
• Ethical rules and lab setups for safe experiments.

Tools & techniques ​

• Signal analysis: ways to monitor and inspect GPS signals.
• Spoofing basics: how attackers can feed fake location data (and how to detect it).
• Jamming: how signal interference works and how to mitigate it.
• Test rigs: building isolated lab environments (VMs, shielded rooms, or Faraday cages) to experiment safely.
• Use this knowledge alongside radios, SDRs (Software Defined Radios), and protocol analyzers.

Who should read this? ​

• Security researchers and students interested in location technologies.
• Engineers building navigation or IoT devices.
• Professionals doing threat assessments for vehicles, drones, and critical systems.
• Hobbyists curious about radio and location security - but follow ethics!

Quick checklist before you start ​

• Set up an isolated test environment.
• Use non-transmitting simulators or shielded spaces when possible.
• Document your methods and findings.
• Share fixes and mitigations responsibly with affected vendors.
