■ Real-time satellite info
• GPS, GLONASS, BeiDou and Galileo shown side by side
• Skyplot: satellite positions in the sky by azimuth and elevation
• Per-satellite signal strength (C/N0), frequency band (L1/L5) and whether it is used in the fix

■ Position, speed and altitude
• Live speed with session max/average and distance traveled
• Altitude above mean sea level (MSL) derived from NMEA data
• Course (true or magnetic north) and compass
• Coordinate formats: decimal degrees (DD), DMS, UTM, MGRS
• Horizontal/vertical accuracy, DOP and fix status

■ Precise satellite time
• GPS time, UTC, leap seconds, clock bias and drift
• Sunrise and sunset times

■ 3D globe map
• Offline 3D globe with vector country and state borders — crisp at any zoom level
• Day/night terminator based on the real position of the sun
• Your track drawn as a past (blue) → present (red) gradient
• Tap a track point to see its time, speed and altitude
• No map tile downloads — works fully offline

■ Location history (optional)
• With your consent, positions are stored only in an encrypted database on your device
• Retention period setting (default 1 day) with automatic deletion
• Delete everything or withdraw consent at any time; export to a file supported

■ Privacy first
• Your location is never sent to any server — everything is processed on the device
• The map renders offline, so there are no location-related network requests
• No account, no ads
• Anonymous usage statistics (never including location) can be turned off in Settings

■ Made for
• Engineers, surveyors and outdoor users who want to inspect GNSS/GPS reception
• Anyone curious how well a new phone receives satellites
• Hikers and travelers who need exact coordinates (incl. UTM/MGRS) and altitude

Note: GPS101 displays the GNSS data provided by your device and OS as-is, for informational purposes only. Do not use it for navigation, surveying, aviation, marine, emergency response or any other safety-critical purpose. Positioning accuracy varies with device, atmospheric conditions and terrain, and may be unavailable indoors. ## Rankings - #3,044,102 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_COARSE_LOCATION` - `android.permission.ACCESS_FINE_LOCATION` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `android.permission.WAKE_LOCK` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `net.daechan.gps101.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [GPS Info](https://chrome-stats.com/d/ch.cri.android.gpsinfo.play) — 13 users - [GPS Satellite: Live Sky View](https://chrome-stats.com/d/com.simonj.gpssatellite) — 83 users - [GPS Test & Satellite Check](https://chrome-stats.com/d/nl.nordicnode.gpssatellitecheck) — 309 users - [GNSS Commander](https://chrome-stats.com/d/pro.petiole.gnss_commander) — 850 users - [GPS Info](https://chrome-stats.com/d/com.fsphost.gpsinfo) — 227 users - [GPS Toolkit – GNSS](https://chrome-stats.com/d/com.twixtech.gpstoolkit) — 548 users - [GNSS Tool](https://chrome-stats.com/d/com.threej.gnss) — 9 users - [GPS Test](https://chrome-stats.com/d/com.chartcross.gpstest) — 20,206,945 users, 3.76 / 5 - [GNSS Monitor](https://chrome-stats.com/d/com.skydronex.gnss_monitor) — 58 users - [GPS Status, Test, Data Tools](https://chrome-stats.com/d/com.ekik.gpsdata) — 1,291 users - [GPS Monitor Pro: GNSS data](https://chrome-stats.com/d/com.signalmonitoring.gpsmonitoringpro) — 31 users - [GPS Monitor: satellite data](https://chrome-stats.com/d/com.signalmonitoring.gpsmonitoring) — 27,133 users, 4.35 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/net.daechan.gps101)
