Are there any specific use cases where this will see outside benefit (urban areas)? Or is it just faster fix and higher precision without PPS/RTK?
inside of the mall when your weather widget pulls your location every 5 minutes they will better know what stores you went in to in what order
I wonder if it's doing L1/L2, or L1/L5...

I though the Apple Watch had its own GPS and used that for signal?
It does have it’s own GPS. But if it tethered with your phone, it uses that instead to save battery life. The same is true for cellular Apple Watches.

based on the keynote, they say it will be better in "urban jungles". It was part of the Apple Watch Ultra and said it worked better for the Boston (IIRC) Maraton. I would hope for the phone it works better for navagation in Car Play... I dont know how many times my phone things, when driving forward, that im turning down a side road...
Source: I watched the keynote and I’ve run both.

All the better to track you with, my dear.
GPS is passive.
Basically Pokemon Go would know you went to the burger shop and not the Hawaian pancake shop 50m before.

The short of it is that for the past two decade or so the us govt has been rolling out a new signal that the latest series of GPS satellites transmit that uses 1. more bandwidth, 2. more transmit power, 3. in a protected region of spectrum, 4. using modern encodings and error correction. This makes it a lot easier to pick up the signal from noisy environments.

When you only way have one radio signal from a satellite, it is impossible to tell how the ionosphere has effected the signal.
When you have two, and each a slightly different frequency, you can model signal path changes and apply some corrections for better general accuracy.
