Take a look at the https://phyphox.org/ app for lower level access to the sensors on Android and iPhones. There is a GPS section that gives you coordinates but unfortunately doesn’t tell you about each satellite. The precision of other phone sensors seems even more amazing.

You could also try https://github.com/barbeau/gpstest if you are looking for something more GPS focused.

That looks pretty cool. Do you know if there is anything similar for iOS, or do Apple prevent apps from accessing those data?

There sure was when I still used iOS. But I don't remember the name.
