Get GPS status and status of GLONASS, Galileo and BeiDou satellites

This app is a tool for displaying the GPS status and the status of other GNSS (global navigation satellite systems). It provides all information about all GNSS supported by your device (GPS, GLONASS, Galileo, BeiDou, ...).

Your location can be shown as latitude/longitude, UTM (Universal Transverse Mercator), MGRS (Military Grid Reference System), OLC (Open Location Code / Plus Code), Mercator, QTH/Maidenhead, Geohash or CH1903+.

Via the "Share" functionality you can share your location to tell someone exactly where you are, this can be very helpful not only in emergencies. Location can be shared as latitude/longitude or as link to all major map services.

Furthermore, functions such as a GPS speedometer, a "Find my car" and a "My Places" functionality are integrated. This makes it possible to calculate and display routes to the location of the car or to other previously saved locations and to be able to navigate there.

The app supports the display of any GPX files with various map services.

New: Record your tracks while hiking, running or cycling, or import GPX files to find the right path while hiking, running or cycling. Export your captured tracks as GPX files. While hiking, running or cycling, you can share your previous route and your current location as a GPX file via email or social networks at any time. The finished GPX file can also be shared via email and social networks. At the recipient of the shared GPX file, clicking on this file opens and displays our app.

Choose between several map providers for the map displays, we also support offline maps!

GNSS Status is an Android application designed to provide users with comprehensive information about the Global Navigation Satellite Systems (GNSS) their devices utilize for location services. It offers a detailed view into the complex interplay between the device's hardware, the available satellite constellations, and the resulting positioning accuracy. The app acts as a diagnostic tool, allowing users to troubleshoot potential GPS issues and understand the factors influencing their location fixes.

At its core, GNSS Status displays a wealth of data related to satellite visibility and signal strength. It visually represents the satellites in view, identifying them by their constellation (GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC) and PRN (Pseudo-Random Noise) code. The signal strength, represented by signal-to-noise ratio (SNR) bars, indicates the quality of the connection between the device and each satellite. Stronger signals contribute to more accurate positioning. The app also displays the number of satellites used in the current fix, highlighting those actively contributing to the location calculation.

Beyond satellite data, GNSS Status offers insights into the device's location accuracy. It displays the estimated horizontal accuracy, providing a measure of the potential error in the reported location. This information is crucial for applications requiring precise positioning. The app also shows the current latitude, longitude, and altitude, along with the time to first fix (TTFF), which represents the time taken to acquire the initial location after starting the app or regaining satellite visibility.

GNSS Status provides a graphical representation of the satellite signals over time, known as a skyplot. This plot visualizes the satellite positions relative to the user's location, offering a clear picture of satellite availability and geometry. The skyplot can help identify potential obstructions or signal interference that might be affecting location accuracy.

The app also includes a sensor status section, displaying information from the device's inertial sensors, such as the accelerometer, gyroscope, and magnetometer. These sensors play a complementary role in location services, particularly in challenging environments where satellite signals are weak or unavailable. The sensor data can be used to estimate the device's movement and orientation, improving the accuracy and reliability of location tracking.

GNSS Status offers a range of advanced features for experienced users. It supports raw GNSS data logging, allowing users to capture detailed information about satellite signals and sensor readings for analysis and troubleshooting. The app also provides access to detailed satellite information, including ephemeris data, which describes the satellite's orbital parameters. This information can be useful for understanding the satellite's position and predicting its future visibility.

Furthermore, GNSS Status supports different coordinate systems and map projections, allowing users to customize the display according to their preferences. The app also includes a built-in compass, providing orientation information based on the device's magnetometer. This feature can be helpful for navigation and outdoor activities.

GNSS Status is a valuable tool for anyone interested in understanding how their devices determine their location. It provides a wealth of information about satellite signals, sensor data, and location accuracy, making it an essential resource for troubleshooting GPS issues, evaluating device performance, and gaining a deeper understanding of GNSS technology. Its user-friendly interface and comprehensive features make it accessible to both casual users and experienced professionals. Whether you are a hiker, a geographer, or simply curious about the technology that powers your navigation apps, GNSS Status offers a fascinating glimpse into the world of satellite positioning.
