GPS Radar: GPS Test & GNSS

Understand your phone’s GPS connection with GPS Radar, a real-time GPS test and GNSS satellite viewer for Android.

See which navigation satellites your device can detect, which satellites contribute to your location fix, and how strong their signals are. The clean dashboard makes detailed satellite information easier to understand without hiding the technical data.

LIVE GPS STATUS

Check your current GPS fix, location accuracy, altitude, speed, latitude and longitude. See the number of satellites currently visible and used for positioning.

GNSS SATELLITE SKY VIEW

Explore a live radar-style sky view showing where detected satellites appear above you. Satellites near the centre are higher overhead, while satellites near the edge are closer to the horizon.

GPS SIGNAL STRENGTH

Compare the live signal strength of individual satellites using clear, easy-to-read charts. This can help you understand whether your device has a strong or weak view of the sky.

MULTIPLE SATELLITE SYSTEMS

View supported navigation constellations reported by your device, including:

• GPS
• Galileo
• GLONASS
• BeiDou
• NavIC
• QZSS

Availability depends on your phone’s GNSS hardware, Android version and current location.

DETAILED SATELLITE DATA

Inspect available information for individual satellites, including:

• Satellite ID and constellation
• Signal strength
• Azimuth and elevation
• Carrier frequency information
• Whether the satellite is used in the current location fix

USE GPS RADAR TO

• Test GPS signal quality
• Check location accuracy
• View visible and connected satellites
• Diagnose weak GPS reception
• Compare GNSS satellite signals
• Understand how your phone calculates its location
• Inspect satellite visibility before outdoor activities

FOR BETTER RESULTS

GPS and GNSS signals generally work best outdoors with a clear view of the sky. Buildings, walls, indoor environments, device hardware and surrounding conditions may affect satellite visibility and accuracy.

GPS Radar displays information reported by your Android device. It does not repair GPS hardware, guarantee a more accurate location, track communication satellites, provide satellite imagery or offer turn-by-turn navigation.
