We've added another PSDS data cache at http://qualcomm.psds.grapheneos.org for devices using Qualcomm GNSS rather than Broadcom GNSS.
We plan to use this to implement our PSDS server toggle for Snapdragon Pixels and future Snapdragon devices we'll end up supporting.

We've added much more detailed information on cellular-based A-GNSS (Assisted Global Navigation Satellite System) to our FAQ:
https://grapheneos.org/faq#other-connections
It explains the difference between control plane vs. user plane A-GNSS, differences between the devices and what we improve.

Our next release will override carrier selected SUPL server (usually supl.google.com) with supl.grapheneos.org by default. Similar to connectivity checks, etc. there will be a new Settings toggle for choosing between GrapheneOS proxy, Standard and Disabled for SUPL.

We're now hosting http://supl.grapheneos.org as a TLS reverse proxy for SUPL:

We'll be replacing our force disable toggle for SUPL with a choice between GrapheneOS, Standard (carrier/fallback) and Disabled.

GNSS (GPS, GLONASS, etc.) uses PSDS to provide satellite almanacs with estimated satellite locations, geographic data, etc. for a faster location lock. We cover this at https://grapheneos.org/faq#default-connections.
A-GNSS is also used to provide a faster location lock via cellular when available.
