Do app devs need to filter location tracking stream?

I'm planning to develop an application for iOS that tracks the user's location and would like to better understand the location data (i.e. coordinates) stream that iOS provides to applications.

In particular does the hardware or platform already employ some kind of filtering for the location stream or is this something that the application developers need to do?

Does this differ per iPhone, iOS version or GNSS system used?

Where could I find more detailed info on this?

Hello Marko, did you ever manage to find the answer on your own? I have been looking into the issue myself starting from this past week and found that the documentation for CoreLocation specifies that it only uses GPS

Requiring the Presence of Specific Location Services | Apple Developer Documentation

According to the page for QZSS (the GNSS I am interested in) the phones do support it, but it is unclear how to access the data stream.
