Android GnssLogger App sample file

[buildvoc10]

1. Aleix was wondering if you have a sample status_log.json file which was extracted from Android GnssLogger App.
2. also could you provide any detail on the extraction process I have read section E. Android GnssLogger App of Improving OSNMAlib: New Formats, Features, and Monitoring Capabilities
   trying to create a dashboard for user to upload android logger to confirm they are receiving raw GNSS data for OSNMA authentication
   many thanks

Hello!

The status_log.json file generated when using the Android GnssLogger input is identical to any other status_log.json file. Find the json schema here.

In any case, here is one from a Samsung 24 (mediatek chipset): status_log.json

You will notice that, even in ideal conditions, the Android reporting of the navigation data is not great. However, in my experience, it is much better in mediatek chipsets than in broadcom chipsets. This problem is starting to improve as more applications are interested in navigation data.

Sure. The GnssLogger app lets you send the logging file to any messaging app as if it was a normal file. You can also access the file in the smartphone storage and extract it as you please (e.g. through USB). Then you need to run OSNMAlib with that logging file as input, and it will generate the status_log.json file.

If you are interested in a real-time execution (i.e. the smartphone sends data directly to a running instance of OSNMAlib), that could also be arranged. The only piece missing is a slightly modified GnssLogger input class to OSNMAlib. If you collect the data in the same format as the GnssLogger app, the implementation should be straightforward.

thanks trying to use https://github.com/buildvoc/OSNMA/blob/docker-deployment/extract.py to extract subframe in a webportal are there any additional steps required?

can you provide an example file from smartphone, having trouble getting validation of OSNMA transmission
