Nice explanation, thank you. I hope this will surface in oss libs soon.

> the Galileo satellites themselves provide properly equipped receivers (not your phone) with near-realtime updates that can be used to achieve very good accuracy.

I have wondered about that. What stops a mobile phone from benefiting from that and RTK?

Hi! So a phone could well benefit from RTK, but this is a local signal, so you have to pick up something that is relevant for your location. Meanwhile, the High Accuracy Service broadcasts realtime corrections, but it does so on a frequency band that is not supported by phone handsets. Also, the RF conditions in most urban environments are such that I'm not sure such corrections would be received well enough to matter in most cases. Phones are moving to dual frequency chipsets which will also improve accuracy without further help. Hope this helps!

Thanks, it being another frequency makes it clear :)

Getting access to local RTK data isn't much of an issue with projects like https://centipede.fr/ and you can always build your own base staion. I was told multiple times that it couldn't work for phones, without elaborating.
