This is a major feature. Network location providers will allow faster results and greater accuracy with locations inside buildings, by default GrapheneOS uses the OS' satellite location (GNSS) for location, with an optional toggle for using Google's existing location service.

For users who want network location and not Google, this network location service would use a GrapheneOS proxy to Apple's WiFi positioning service. Users may choose to not use the proxy.

Eventually, we'll be making our own local database using scraped data from Apple's service to implement network location and SUPL for users who want network-based location without connecting to them.
