GPS101 - GNSS Dashboard

GPS101 is a real-time satellite dashboard that shows your device's GNSS reception at a glance: which satellites your phone is tracking, how strong their signals are, and how accurate your fix is — all on one screen. ■ 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.
