Hello and thank you for your great work on UT! What about the integration of connectors for streaming services such as Spotify, Tidal or Deezer directly into the native UT music application?
Cheers

Hi everyone, I'm currently using the Messwerk application (https://open-store.io/app/harbour-messwerk.mymike00) in order to get raw data from the GNSS receiver on my Nexus 5 phone.

It seems that the log function of the GNSS positions and satellites data isn't working well ; on the other hand, accelerometer and rotation data are normally logged.

I haven't found how to reach the creator of this app (Michele Castellazzi) or raise any issue on the GitHub project.
Could someone please help me get in touch with the development team?
Thanks a lot.

@poVoq I agree with you AGPS is here to improve the Time To First Fix (TTFF) but it has no influence on the positioning accuracy.
We would just need to find out what output of the Nexus 5 GNSS receiver is used in UT; most of the time a receiver offers different types of outputs, more or less accurate: GPS alone, GPS coupled with GLONASS (seems like the Nexus 5 GNSS receiver uses both constellations), GPS coupled with SBAS (WAAS over the US, EGNOS over Europe, etc.).
Maybe we should get in touch with the developers of UT regarding this specific issue in order to find a way to improve the positioning accuracy. How can we reach them on that subject?

Ok thanks I better understand your problem.
Just a quick question: are you satisfied with the positioning accuracy when you're using apps such as Pure Maps, Unav or Utrack?
I'll continue to try to find out why there's such a poor positioning accuracy (in my point of view) on the Nexus 5 and what could be done to improve it.

@normandc Hello, I'm using Pure Maps on Nexus 5 and I'm experiencing the same problem regarding the "unreliable GPS location".
Having a look at the SensorsStatus app, it seems normal not to have a pinpoint accuracy because the indicated "accuracy" (which indeed might be the standard deviation computed by the GPS receiver itself) is never under around 10 m.
So I have another question pending: is it possible to find a datasheet of the GPS receiver? That would be helpful to know what's behind the receiver's outputs (GPS alone? GPS + GLONASS? GPS + SBAS?) and to know if the observed positioning accuracy is consistent or not with them.
Thanks for your help, and as I'm pretty new here, if there's on this forum a dedicated section for GPS receivers on UT phones feel free to tell me but I haven't found it yet
