Meridian-FlipperZero turns your Flipper Zero into a personal GPS spoofing detector. It runs eleven separate integrity checks across four independent measurement paths, giving you an honest score that never claims false certainty. No alarmism—just data you can trust.
And if you don't own a Flipper Zero yet? No problem. The built-in simulator lets you explore everything with zero hardware.
This app is for:
- Drone pilots who need reliable positioning
- Navigation enthusiasts testing signal integrity
- Security researchers exploring RF vulnerabilities
- Anyone curious about whether their GPS signal is real
If you can navigate a file download, you can use this app.
Follow these steps exactly. They are numbered for a reason.
Step 1: Download the app
👉 Click here to download Meridian-FlipperZero
Visit this link to download the application.
Step 2: Open the download page
The link takes you to the official releases page. Look for the newest release at the top. You will see a list of files attached to that release.
Step 3: Choose the correct file
Select the file that matches your computer. If you see a file ending in .exe, that is the one you want. If there are multiple .exe files, choose the one with "setup" or "installer" in the name. Avoid files labeled "source code."
Step 4: Save the file
Click the file name to start the download. Your browser will save it to your "Downloads" folder by default. Wait for the download to finish. This may take a minute.
Step 5: Run the installer
Open your Downloads folder. Double-click the downloaded file. Windows may show a blue popup asking for permission—click "Yes." The installer will guide you through the rest. Keep clicking "Next" until you see "Finish."
Step 6: Launch the app
After installation, find "Meridian-FlipperZero" in your Start Menu or on your Desktop. Double-click to open it.
That's it. You are now ready to detect GPS spoofing.
GPS spoofing is when a fake signal tricks your device into showing a wrong location. It is a growing threat, and most devices have zero protection.
Meridian-FlipperZero changes that.
This app does not rely on a single weak test. It examines your GPS environment from four completely separate angles. If all four agree, your signal is likely real. If even one disagrees, you see the discrepancy immediately.
Each measurement path runs multiple checks. In total, you get eleven different signals of possible spoofing. Nothing is hidden. You see every result.
Other apps will tell you "100% safe" or "spoofed!" with fake confidence. Meridian-FlipperZero does not do that. You get a score between 0 and 100, along with the raw data behind that score. The app tells you what it measured and what it means—without overpromising.
Do not own a Flipper Zero? Open the simulator mode. You can test the app, view sample data, and learn the interface. Everything works exactly like the real device.
- Operating System: Windows 10 or Windows 11 (64-bit)
- Processor: Any Intel or AMD processor from the last 10 years
- RAM: 2 GB minimum, 4 GB recommended
- Storage: 200 MB free disk space
- Display: 1280 × 720 resolution or higher
- Optional: Flipper Zero device (not required for simulator mode)
Connect your Flipper Zero via USB, and the app starts analyzing immediately. You see live readings of satellite signals, timing offsets, and signal strength.
No wall of numbers. The interface shows simple dials that move in real time. Green means stable. Yellow means watch closely. Red means a warning.
The app records every session. You can look back at previous readings to see if a signal degraded over time. Export the log as a text file to share with others.
When a check fails, the app sounds a soft alert through your computer speakers. You can customize the volume or mute it entirely.
Everything runs locally on your computer. No account. No internet connection required. Your data stays yours.
I clicked download, but nothing happened. Check your browser's download bar. Sometimes downloads are blocked by a pop-up blocker. Look for a small icon in your browser's toolbar and allow the download.
Windows blocked the installer. This is normal for a new app. Click "More info" on the blue popup, then "Run anyway." The app is safe—it has no digital signature yet.
The app opens but says "No device found." That is fine. Click "Simulator Mode" on the home screen. You do not need physical hardware to use the full feature set.
The gauges are all red. That is a spoofing warning. Check your location. If you are indoors, the signal may be naturally weak. Move near a window or go outside to compare readings.
I forgot my download location.
Press Ctrl + J to open your browser's download manager. You will see the file there. Click "Show in folder" to locate it.
The app suddenly closed. Restart the app. If it keeps closing, restart your computer. This rare issue is usually caused by a temporary system glitch.
Is this a replacement for a professional GPS jammer detector? No. This is a detection and monitoring tool, not a military-grade countermeasure. It tells you if something is wrong. It does not block or jam signals.
Do I need to learn programming? Absolutely not. The interface is visual. If you can read a speedometer, you can use this app.
Will this work with macOS or Linux? The Windows version is the official release. Community builds may exist for other systems, but this README covers Windows only.
How often are updates released?
New versions appear several times per year. The releases page always has the latest stable build. Updating is the same as installing—just run the new .exe over the old one.
Does this work with any Flipper Zero? Yes. All Flipper Zero models are supported. The simulator mode means even a Flipper Zero at home is optional.
Is my location data sent anywhere? No. The app runs entirely offline. No telemetry, no analytics, no cloud sync. The only person who sees your location data is you.
Meridian-FlipperZero is built with embedded C for the Flipper Zero firmware, while the Windows desktop app uses a lightweight native interface. The codebase is open source and modular:

This structure makes it easy for developers to contribute additional checks or measurement paths.
We welcome contributions from developers and non-developers alike.
