GPS Satellite is the most accurate GPS satellite tracker, GNSS signal scanner, and live sky view for Android. See visible satellites with SNR strength, fix status, and constellation in seconds.
Whether you check phone GPS health, find best signal location, or learn about GNSS — GPS Satellite turns your phone into a precision satellite signal analyzer.
▶ MAIN FEATURES
• GPS satellite tracker — live visible satellites with SNR
• GNSS scanner — GPS, GLONASS, Galileo, BeiDou, QZSS
• Live sky view — satellite positions on a polar chart
• Signal strength meter — per-satellite SNR (dB-Hz)
• Fix status — 2D/3D fix and HDOP indicator
• Speed and altitude readout
• Coordinates display: lat/lon, MGRS, UTM
• Calibrate with known altitude reference
• Dark mode for outdoor use
• Works fully offline (after first GPS fix)
▶ HOW TO USE
1. Open GPS Satellite outdoors with sky view
2. Wait 30 seconds for satellite acquisition
3. View the polar sky chart with live satellite positions
4. Check SNR per satellite — green = strong, red = weak
