Hello!
I'm not sure this is a stock behaviour: I never saw it happen on factory stock, but it also happened once on stock after I returned temporarily to stock.
Anyway, on GOS stable, Pixel 6a, using Google Maps with all Google's features enabled, including Bluetooth and Wifi helpers, if I leave Maps open and keep looking at it, while still, indoors (not sure if happening outdoors too, probably not), sometimes my location jumps by 500 meters.
My assumption is it is using A-GPS. But why? It seems to cycle through all available precision and sources -- GPS, AGPS, Wifi, Bluetooth before returning to the precise location.
Any tips on how to debug?
