#3Article about what dual-frequency GPS is: https://www.zdnet.com/article/what-is-l5-precision-dual-freq...
It says that GPS has added a new band (L5) that works better indoors. Combining it with traditional L1 gives better results. L5 is not fully deployed.

#4afaiu this also means that every non-Ultra Apple watch will benefit from dual-frequency GPS when paired with an iPhone 14

#5Support for Galileo and Glonass was touted maybe a decade ago, but there was never any massive improvement in accuracy. Same story?
Even worse, Apple Maps still freezes after I leave a tunnel - I’ve been through at least 3 different models in the meantime.

My team and I are watching you as we speak. Spoiler alert: Your tinfoil hat doesn't help.

Dual frequency mitigates the ionospheric delay error of GPS signals, yielding more accurate measurements.

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.
