What is GPSA ?

GPS assisted (hence the A) by mobile cell towers.

My uneducated guess is that it actually has something to do with how well GPSA works on a particular network - will see what Marius thinks about my theory
Oddly, it worked earlier when I posted. Now that I've had more free time, I'm unable to get GPS working.
Used https://gpsd.gitlab.io/gpsd/installation.html as a reference to test the GPS and it does seem to be found, but nothing is coming back?

?WATCH={"enable":true,"json":true};After watch, nothing is returned. I did verify that the gpsd service wasn't running. Phone also has a clear view of the outside. I'll reflash and try again as I have been doing OTA since release. Based on the above output, seems something broke.
Well this is fun... is the latest image broken?
Just downloaded a fresh image from Jenkins, https://ci.ubports.com/job/rootfs/job/rootfs-pinephone-systemimage/, and found gpsd / ubuntu-location-service were missing from init.d. Redownloaded the image again and found I have the same file. Odd... The gpsd service listed below is due to me running "apt install gpsd" as an attempt to fix.

(05-18-2020, 02:43 PM)Luke Wrote: Here are the steps to enable and help testing GPS on Ubuntu Touch.
I strongly suggest you open SSH first:
Code:sudo mount -o rw,remount /
sudo umount /etc/init/ssh.override
sudo rm /etc/init/ssh.override
sudo start ssh
Step 1)
You need to be using OTA version 27 (May 17th) or newer. You should be on devel channel.
Step 2)
Fetch uNav and Pure Maps from OpenStore
Step 3)
Mount the volume so its rewritable
Code:sudo mount -o rw,remount /
Step 4)
Install gpsd
Code:ubports-qa install xenial_-_edge_-_gpsd
Step 5)
Start GPS + some magic
Code:sudo /etc/init.d/gpsd start
sudo restart ubuntu-location-service
initctl unset-env --global UBUNTU_PLATFORM_API_BACKEND
initctl set-env --global UBUNTU_PLATFORM_API_BACKEND=touch_mirclient
Step 6)
Open uNav and request it to fetch your location.
Report issues, fixes, ideas and everything else related to the topic of location services on Ubuntu Touch in this thread.
Luke (or any helpful person?,
I have been a bit of a Smeghead. I was unable to get this to work unfortunately. I will continue to try. However, I mistakenly have appeared to remove the PPA from my phone, getting the message "CRITICAL:ubports-qa: PPA not found".
Is there an easy way to re-install it? I tried the usual way (or so I thought), but was not successful.
Thanks,
Pinetop Perkins
RE: Testing GPS - ozymandium - 05-24-2020
Would it be correct to assume, then, that we're getting GNSS messages via NMEA strings over UART, and gpsd is just parsing those?

That's correct - NMEA received via a one-way USB serial interface. Config, enabling and disabling is done via AT commands over one of the other USB serial interfaces. i assume ubports is doing the same as pmOS by giving gpsd commands to enable gps when the first client connects, and disable it when the last one disconnects.
RE: Testing GPS - pfeerick - 05-26-2020
Just gave this a spin, didn't have any luck... (after realising that perhaps I needed to turn the modem back on again!) ... wifi performance seemed to take a turn for the worse, and didn't seem to get a GPS lock at all. uNAV did place me in the right country, but it was using IP geo-location, not GPS, so thought I was in Brisbane, where my ISP's endpoint is.
RE: Testing GPS - kugiigi - 06-03-2020
Pure Maps and uNav just crashed on mine ?
