About this app

Discover Earth's invisible atmosphere layer using your phone's GPS signals

🌐 What is IonoScope? IonoScope transforms your dual-band GPS smartphone into a scientific instrument for measuring the ionosphere - Earth's charged atmosphere layer that affects radio signals and satellite communications.

📱 Turn Your Phone into a Space Weather Station • Measure Total Electron Content (TEC) using L1 and L5 GPS frequencies • Track ionospheric density changes throughout the day • Visualize satellite signals passing through charged atmosphere layers • Save and share your measurements with the scientific community

🎓 Learn While You Explore • Interactive lessons explaining ionosphere science • Step-by-step tutorials on GPS signal propagation • Real-world examples of how ionospheric conditions affect technology • Hands-on experiments with dual-frequency measurements

📊 Advanced Features • Real-time GNSS measurements from multiple satellite constellations • Historical session logging and data export • CSV and JSON data sharing capabilities • Device compatibility checking for optimal measurements

🔬 Perfect for: • Students learning about atmospheric science • Amateur radio operators tracking space weather • Educators teaching GPS and ionosphere concepts • Anyone curious about invisible forces affecting our technology

Requirements: Android device with dual-band GPS support (L1 + L5 frequencies) for ionospheric measurements. The app includes device compatibility checking and works with educational content on all devices.

Note: Best results on newer Android devices (2018+) with advanced GNSS chipsets. The app includes guided lessons that work on all devices, with live measurements available on compatible hardware.

What’s new

New feature: Long-term recording with background logging (minimizing the app preserves recording state).
