GnssLogger by Google enables in-depth analysis and logging of all types of location and sensor data such as GPS (Global Positioning System), network location and other sensor data. GnssLogger is available for phones and watches. It comes with the following features for phones:HOME TAB:
● Control various data logging such as raw GNSS measurements, GnssStatus, NMEA, navigation messages, sensor data and RINEX logs.
LOG TAB:
● View all location and raw measurement data.
● Control offline logging using 'Start Log', 'Stop & Send' and 'Timed Log'.
● Enable specific items to be logged using corresponding switches in Home Tab.
● Delete existing log files from disk.
MAP TAB:
● Visualize on GoogleMap, the location provided by GPS chipset, Network Location Provider (NLP), Fused Location Provider (FLP), and computed Weighted Least Square (WLS) position.
● Toggle between different map views and location types.
PLOTS TAB:
● Visualize CN0 (Signal Strength), PR (pseudorange) Residual and PRR (pseudorange rate) Residual vs time.
STATUS TAB:
● View detailed information of all visible GNSS (Global Navigation Satellite System) satellites such as GPS, Beidou (BDS), QZSS, GAL (Galileo), GLO (GLONASS) and IRNSS.
SKYPLOT TAB:
● Visualize the data of all visible GNSS satellites using a skyplot.
● View the average CN0 of all the satellites in view and the ones used in fix.
AGNSS TAB:
● Experiment with Assisted-GNSS functionalities.
WLS Analysis TAB:
● View the Weighted Least Square position, velocity and their uncertainties computed based on raw GNSS measurements.
● Compare the WLS results to the GNSS chipset reported values.
It comes with the following features for watches running Wear OS 3.0 and higher:
● View real-time GNSS chipset status information.
● Log various GNSS and sensor data to CSV and RINEX files.

This app is amazing, thanks a lot for developing it. But, there are still gaps into the raw measurements, it is something like it freezing after one hour, or two. After a freezing of approximately 3 hour, it starts again to measure which is very uncomfortable. (all battery optimization options are disable for this app). Thank you so much!

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)

Edit: version 3.0.6.1 fixes the problems I had, everything works great now. Thanks for the communication, devs! Original review below: Signal strength plot doesn't seem to work at all. Yes, I've tried it outside. Status and Skyplot tabs show satellites, Map shows my location. The problem is with the Plots tab not displaying any graphs, only an empty white area, with the text "No Measurement has been received yet. Please turn on Measurement and Location in Home tab." Yes, they are both enabled.

App broken, was good before the option to download the data jumped from sending emails to wanting to uselessly text the large datafiles. There is no way to reset this, even uninstalling and reinstalling keeps this setting which means it is impossible to use the program for any serious testing. Even before this very serious bug getting the data out was flakey as it was easy to press wrong part of screen, loose the option to download and have to repeat the experiment. UPDATE, reset apps and fixed.

Good app! But I have a question, why is there a difference between weighted least squares solution and GPS provider? Whereas GPS system uses WLS. Maybe there are corrections (using sensors and Wi-Fi for example) but in this case, what is the difference between fused location and GPS provider? Thanks

I am getting much better performance after the recent update. Now that it works, I am very happy with this app. It is great for GNSS analysis. My two only gripes. I can not figure out how to log sensor data. When I check Log Sensor on the main screen, nothing additional shows up in the log. And my second gripe is that the log clears everytime I go to another screen, even with the app running in the background, so I can't log data while using Google maps to navigate.

On Pixel 4, the app is very slow and often freezes in sensor (IMU) + RINEX logging mode. There is not 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?

Excellent app, thank you for the great work. The timed logging function is great, but Is there a way to adjust the data logging interval by user, say every minute or every half/hour etc.? A setting like that would be helpful.
