Hi Marcel
Thanks for posting your code.
In the meantime I have dug out and posted the SatInfoSource demo I
played around with at Christmas - at the time on the Emulator (my
Jolla only arrived on the 30th Dec).
https://github.com/sailfishapps/ThrowawayDemos/tree/master/Kaputt/SatInfoSourceDemo
Running this on the real Jolla you will see in the application output
that is no SatelliteInfoSource installed. So we need to work out if
there is a plugin that provides this, and install it.
The plugins should have a jason file with values like:
"Position": true,
"Satellite": true,
See the link below for more info.
http://qt-project.org/doc/qt-5/qtpositioning-plugins.html
When I last looked (Qt 4.8 Mobility Location 1.2) there was no
SatelliteInfoSource exposed to QML "out-of-the-box". After studying
the source code I think the reason was down to the problem of
exchanging lists between C++ and QML. I would need to wade deep in the
code again to explain more precisely / accurately.
As all I needed was the number of Satellites in view / use I just
wrote my own plugin to expose that to QML. C++ is not my main
programming language - I follow the cut-and-paste school, so the code
may not be the best reference, but it did work for my purposes. By all
means adapt it if you want.

Hi Chris,
I've pushed my existing code to github for you, but be warned, it is chaotic,
and my first "real" qt project. There is a lot to do...
https://github.com/balta3/sailfish-gpsinfo
The QML position source is working here, and you can see the compass access,
too. Is there any existing QML component for SatelliteInfoSource? I try to
access it in C++ as I could not find any in the Qt documentation.
Greetings,
Marcel

Hi Marcel.
The fast response is pure self interest - I am fighting with GPS code
myself right now!
Are you using SatelliteinfoSource from C++ or QML?
on Harmattan I wrote my own C++ plugin to expose SatsInuse and
SatsInView to QML as this was not available in QML for Qt Mobility 1.2
Location.
If you have example of working QML PositionSource code I would love to
see it, as I get errors when I call the start() method on a real Jolla
- this is the subject of another thread which I will update in the
next few minutes

Chris
p.s. I think during Christmas I wrote a throwaway demo for
SatelliteInfoSource on Qt5, I will dig that out again and give it a
whorl on my Jolla.
