Galileo support for Xperia X

For Galileo support has been asked before.

But as the Xperia X hosts a Snapdragon 650 the question here is a bit different. It's not about porting SFOS to a device that supports Galileo positioning, but it's about SFOS supporting Galileo software wise (as suggested in one answer from above thread).

I have the impression, that the topic needs its own question. So: are there any plans to support Galileo positioning in SFOS in the near future?

Never heard of this, but got curious and looked into it. Galileo site says it's either built into the chip or it isn't. You need only to install a gps info app and see if it shows up.

You can get the app here -

thats android "SubSystem". you need to validate that on sfos.

Are there any SF apps that show gnss?

Galileo doesn't really need any support from Sailfish OS side and it should work if Android release used as the base for the device supports it. I'm not sure if Xperia X has support for Galileo in Android or not. It's completely different thing that QtLocation doesn't report satellite system in Sailfish OS and it's not related to using of Galileo satellites for location.

Well, the Chipset of the Xperia should support it (see - choose chipsets look for Qualcomm Snapdragon 650), but Sony only states A-GNSS (GPS + GLONASS) and the same page from link before only lists Sony XZ, X2, XZ2, XZ1 as supported. On the other hand I can't think it to be impossible, as the chipset is supported and android HAL probably should support it chipset wise and not for specific devices, or am I wrong?

I would say :

  • Galileo uses slightly different frequencies than both GPS and GLONASS. The Xperia X might be lacking the corresponding radio and antenna equipment and thus not be able to catch the signal, even if the navigation core of the Snapdragon would have been capable of decoding it.

  • Some of the earlier GPS+GLONASS+Galileo cores (I have no idea if it applies to Snapdragon 650) can only either decode GPS+GLONASS or GPS+Galileo but not both at the same time. If that's the case, extra software is needed to switch between the two modes. (Exactly the same is reported to happen with the earliest core that started adding chinese Beidou in the mix).
