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.
- toomuchtodo 4y agoAre 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?
- tiernano 4y agobased 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...

- willis936 4y agoThat last bit is a software issue. Apple maps is constantly trying to route me to a parallel street for 1 block in a city and it actually thinks I listen to it. Google maps doesn't have either of these behaviors on the same hardware/APIs. No, a more accurate GPS will not fix Apple's bugs.

- dylan604 4y agoWouldn't the WiFi and Bluetooth beacons provide more accurate and more granular points of data than polling GPS for this purpose?
- capableweb 4y agoThat would require calibration (this is the layout of the store, the receiver is here, reflections can occur here and so on) while a GPS system would allow owners to just connect to a centralized app and bam, here is where all your visitors walked for the last 3 months.
- dylan604 4y agowow, that's your retort/sales pitch for GPS only tracking? it truly needs some work.
- capableweb 4y agoNope, it's simply information, free for everyone to read :) I'm neither selling or arguing for/against anything.
- fsh 4y agoDual-band GPS allows detecting (and correcting for) multipath interference, i.e. signals bouncing off building and being received multiple times. This should improve accuracy in cities a fair bit.
- throw0101c 4y ago> Are there any specific use cases where this will see outside benefit (urban areas)? 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.
