Cool. I guess the Chinese agency that manages the system must have set them available or operational or whatever that tag is that lets receivers know that they are there for a legitimate fix. I checked my phone after you posted, just in case. I didn't think it likely, and it's still getting its fix only from GPS and Glonass constellations.
You mentioned:
"I hope that the proposed large constellation of interrnet satellite does not interrupt GNSS."
Agreed. Like any radio transmitters, there is always a risk of signal noise causing accicental jamming, but I think it's worth recognizing that this applies to any new radio transmitters including things like baby monitors and WiFi doorbells. Is there any specific reason to worry about the signals from the StarLink constellation affecting GNSS? It doesn't make any real difference that the new transmitters on the internet satellites (like SpaceX's StarLink satellites) are "up there" except that there's a rather large ground footprint of visibility for a single satellite, and that could be an issue. But if any one satellite is behaving badly, it would have to be shut down to comply with US FCC rules, at least when operating within an FCC license.
I'm already thinking about these StarLink satellites for visual navigation fixes, but they're rather faint. I observed a few of them three days ago, and they were around magnitude 4 or fainter on favorable passes. Plus they're not visible at all for a few hours around local midnight.
