for UK riding, using a Garmin 130 :
GPS
GPS + GLONASS
GPS + Galileo
thanks.
I think that theoretically Galileo will be most accurate but try it and see. Whether or not that will be 'best' depends on what you are doing as I believe that battery life is poorer when using two systems rather than just one. GPS by itself is normally just fine
Interesting, thanks. I have been using it since I got it a few months back on the basic GPS setting and it’s been great. I did however try it indoors today at the Glasgow Velodrome (without speed and cadence sensors, which I have now ordered ! ) and it was crap and got all confused !

erm, what did you expect indoors with no GPS signal?
It had a GPS signal in the Velodrome, but I guess not a very good one 😜
Velodromes or other tight circular routes are horrible for this sort of thing. The signal isn't fantastically accurate while you are moving so the software tries to fill in a bit. On a circular route this seems not to work too well as I guess it has difficulty working out the shape. On a trail this isn't so much of an issue
I didn't think Galileo was full operational until 2020. I think a few satellites have been launched, but they haven't got the full constellation up yet.
Useful info, thanks. Will try it on the track with GPS on plus speed and cadence sensors and see what it does, and can then try with GPS off, cheers. It auto loads to Strava which probably messes it too 😀

I thought they were getting closer. Something like 26 satellites out of 30 actually up, 14 operational at the moment out of the 24 they need for full coverage.
Isn't there meant to be a Chinese one at some point as well or did that idea get binned
Yes, the Chinese system is Beidou, aka Compass. The first version only covered China and surroundings, but I think it now has mostly worldwide coverage.
I don't think any Garmins support it yet. It seems some phones can. I've tried a GPS test app on my phone, and it sees some Beidou satellites, though not sure if it is actually using them for positioning.
All of these fancy Dan Chinese Beidou, Russian Glosnass and Euro Galileo systems will of course be rendered utterly obsolete post Brexit when Britain will launch its own system.
You're going round in a circle. Do you need your GPS to stop you getting lost?
