The Android GnssLogger app logs data in the user-selected formats, including RINEX. GnssLogger can run for hours or days, assuming the device has enough storage. Do test runs to be sure unnecessary other data files aren’t also stored as they can be much larger than the RINEX data.

Android Raw GNSS measurements are available on numerous listed devices.

When clicking “save and send” to end a logging session, the app asks where to save in the cloud. Simply canceling the upload retains the data in the “Downloads” folder on the device. This can be useful when the device has a low-bandwidth or expensive data connection, and the data can be uploaded later or copied to a computer via USB.
