Offline GPS localization

Hello,

From the limited technical knowledge I have on this subject, I understand that you are using microG to replace the services normally provided by Google. And that UnifiedNlp is used with Mozilla Location Service to allow the use of GPS. But from what I understand, Mozilla Location Service can only work if you have an internet connection, so you need a data connection.
So for people like me who don’t have a 4G connection, I’d like to know if you were planning to add another location provider that allows offline use.

Thanks for this great project.

Hi, for what is an offline location needed ???
GPS is normally only working out side and do not need any data connections. You only need a data connection if you what see a map.
For the actual location is used GPS, Wifi or mobil service.

This is a fairly old thread, but I hit that same issue yesterday, ending up looking for my way the old way.

Problem is, even though I have the maps downloaded in Maps.me and OSMand, I don’t have any data left on my monthly subscription, so I can’t use any kind of external connection. I set the phone on GPS only in a desperate attempt, but impossible to get any signal.

So yes, being able to use GPS while being off wifi / data would be super useful, same goes for travelling to remote places.

Thanks for all that information @anon64684597 . This issue is very new to me (I’ve been on stock Android for few years since cyanogenmod…), so I don’t what problem I am hitting, but I still don’t get any decent signal when I try using location on its own.

I’ll try to find time digging into this, I’ve installed all the apps you mentioned, now I need to understand how this all works.

I know it’s been a while but… I noticed there are some UnifiedNlp backends which support offline mode:
