Comments on GnssLogger App for Android

★★★★★ 娄学正 · Aug 6, 2021

I found a bug while I use your GnssLogger APP, there are no carrier phase measurement in the rinex file. My device is Oneplus 9R.

★★★★★ JohnnyJim J · May 17, 2025

Incredibly feature-rich app in an incredibly small package. VERY accurate GPS positioning, altitude and compass! I just wish my Google Pixel 9 Pro XL could use its engine for storing picture GPS location instead of the camera's built-in engine, which is extremely inaccurate (it wanders all over the place and can be off by hundreds of feet even outside)

★★★★☆ Raj Gaurav · Sep 9, 2021

Tried collecting GNSS data along with RINEX. The app stops logging and working and device stops working for few minutes. I was using Mi10 5G.

★★★★☆ Markus Kuhn · Jun 29, 2021

Useful app for getting raw pseudo-range data out of the GNSS receiver. However, while this works fine in the gnss_log_*.txt file generated (which does contain many lines starting with “Raw,”), when I send the log via email, the also generated RINEX file gnss_log_*.21o sadly is nearly empty: it contains, apart from a 10-line header and once-per-second timestamp lines, only lines consisting of the 3-character satellite identifiers. No observation data or anything else. This is on a Google Pixel 3. This problem still exists in v3.0.0.10.

★★☆☆☆ Zhiheng Cao · Jul 28, 2021

On Pixel 4, the app is very slow and often freezes in sensor (IMU) + RINEX logging mode. There is no problem with sensor (IMU) + raw GNSS measurement data txt format. I suspect it is because the live format conversion to RINEX is taking too much CPU on the phone? Is there a way to convert the raw txt format data from this app into RINEX on a PC or after the logging is finished?

Trust & Safety: The app requests location permissions (ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION, ACCESS_LOCATION_EXTRA_COMMANDS), network state, activity recognition, foreground service, internet, and notification permissions, among others.
