Galileo enabled android tablets

[Olivier]

Dear Group,

I hope it's OK to ask here, even if my question doesn't directly relate to GPS Test...

I found some information/lists about Galileo enabled android phones (on this group, on usegalileo.eu, ...) but nothing about Galileo enabled android tablets.

Do you know of any such list, or do you have some Android tablet in mind that are Galileo enabled (for affordable field survey) ?

When GPS specs looks like "Yes, with A-GPS, GLONASS, BDS" (on gsmarena.com, for the Huawei MediaPad M3 Lite 10) does it mean that it's also supporting Galileo, as it's already multi-constellation ?

If so, is that enough to expect the sensible accuracy improvement in challenging environment ESA is promising, or does it need to be dual-band, where GPS specs look like "Yes, with dual-band A-GPS, GLONASS, BDS, GALILEO, QZSS" (still on gsmarena.com, for the Xiaomi MI 8) ?

Thanks in advance !

1. about gsmarena
at the end of specs page we can read
Disclaimer. We can not guarantee that the information on this page is 100% correct.

2. about specs (from gsmarena)
when we read "  GPS      Yes, with dual-band A-GPS, GLONASS, BDS, GALILEO, QZSS"
i think it's not OK

I think this is the right description " GNSS  with support for dual band of the follow systems GPS, GLONASS, BDS, GALILEO, QZSS"
about A-GPS, this feature is from GSM modem. We must have sim inside the device for this extra option.
GNSS receiver can work as stand alone hardware.

3. about Galileo
we must visit manufacturer device page into the web to see the specs. This is only 100% guarantee

Galileo transmit both L1 + L5 frequencies (soon or late "2020 and more"). So, it can work with GNSS receivers with one band or dual band

Olivier,

Sure, posts on related topics here are welcome.

I don't know of any official sites other than https://www.usegalileo.eu/EN/ that would list Galileo-enabled tablets.

Generally speaking, I'd assume most off-the-shelf devices these days that are multi-GNSS would also include Galileo.  However, there are geographic restrictions on Galileo use - for example, the FCC hasn't granted a license for devices in the U.S. to use Galileo satellites, so even if the hardware supports Galileo devices are geo-fenced to exclude Galileo when within the U.S.:

I believe the same applies to BeiDou.

If so, is that enough to expect the sensible accuracy improvement in challenging environment ESA is promising, or does it need to be dual-band, where GPS specs look like "Yes, with dual-band A-GPS, GLONASS, BDS, GALILEO, QZSS" (still on gsmarena.com, for the Xiaomi MI 8) ?

In theory the more satellites visible the better your fix should be, assuming you're in an area where the GNSS in question can be used.  Dual-frequency GNSS should see an accuracy bump beyond L1 signal accuracy, although in practice this is still emerging.  See the following for more info:

An update - I have it on good authority that the next upcoming release of UseGalileo.EU will include both tablets and wearables.

FYI - the "Going Mobile" section of the UseGalileo.EU site now features chipsets, "wareable and sport devices", and "smartphones/tablets":
