The Android Framework provides access to raw GNSS measurements on several Android devices.
Note:
Google has released version 2.6.1.0 of the GNSS Analysis App. For more information, see the GNSS Analysis app v2.6.1.0 release notes.
This article lists Android devices that support raw GNSS measurements as well as tools to log and analyze GNSS data. You can find the tools in the GPS Measurement Tools repo on GitHub, which includes the GNSS Logger APK and the GNSS Analysis app for Linux, Windows, macOS, and the Installation and User Manual.
Original equipment manufacturers (OEMs), developers, and researchers can make use of the tools in this page to test new phone designs, validate functionality, develop new algorithms, evaluate improvements to the GNSS system implementation as well as building value added apps.

Android devices that support raw GNSS measurements
Before you can get any raw GNSS output, you need to make sure that you have a device that can capture such data. Most devices manufactured in 2016 or later and shipped with Android 7.0 or higher provide raw GNSS data.
Depending on the device, raw GNSS measurements can include all or some of the following data:
- Pseudorange and pseudorange rate.
- Navigation messages.
- Accumulated delta range or carrier.
- Hardware (HW) clock.
The table below lists devices that support raw GNSS measurements and the data they provide. This isn't a comprehensive list, you should contact the manufacturer to make sure that a specific device supports raw GNSS measurements.

For more information about the data provided by a device, see Global Navigation Satellite Systems.
Logging raw measurements
You can use Android Studio to build an app that captures raw GNSS measurements and logs them to a file. The GPS Measurement Tools project includes GNSS Logger, a sample app that shows how to log data related to Android location, including raw GNSS measurements.
Download the GNSS Logger APK to install the sample app in your device.
To get GNSS output with the sample app, your device must support raw GNSS measurements. For more information, see Android devices that support raw GNSS measurements.
Once you have captured the GNSS log using the GNSS Logger, you can copy the log files from the device to your computer for further analysis. From within the GNSS Logger you can send the files to yourself via email or save them to Google Drive. Alternatively, you can save the files using the file management app on the device, or you can use the Android Debug Bridge (ADB) as explained in Copy files to/from a device.
To browse the sample source code, see the GNSSLogger folder in the GPS Measurement Toolsrepository on GitHub.
