iPhone 15 Pro GPS is worthless!

[mdolan92869]

Beyond my pay grade.

My GPS receiver was whatever Boeing stuck in the airplane. That in turn was determined by how much my employer was willing to pay. If they could’ve gotten away with us sitting on orange crates while using a whiskey compass and following steamships, we would’ve been doing that. Absolutely, Positively.

As for my iPhone 15 ProMax, I got stuck with whatever Apple had laying around when it was thrown together, despite actually paying retail for it.

I guess I did get what I paid for with the cheap GPS add-on for my DSLR so I could automatically tag my pictures like I do on my phone. Didn't realize that it also set my camera clock for me. ?‍

Back when I was learning to fly in the early 90s, I was working at Hughes Aircraft playing with GPS stuff for my job. Bought one of my own and all my instructor wanted to do was play with it during my lessons, seeing how good it was compared to where we actually were. Here I am, barely soloed and she's rustling charts all over the place waving this big ol' GPS unit all over the cabin making sure she had a signal. I asked if this was a distraction lesson, seeing if I could just concentrate on flying.

It’s actually amazing just how accurate gps is and just how much it has permeated our lives. Not terribly long ago we’d see aircraft contrails all over the place while flying the exact same route. Now we have them stacked up right on top of each other and get upset our car is showing up in the CarPlay map 1/10 of a mile off.

to be fair, the car is further away from the satellites. lol

15 hour flight, literally halfway around the world. Arrive after dodging thunderstorms towering to 60,000 feet plus. Awake for almost two days and land in a damn blizzard with visibility around 1/2 mile in snow and 35 knot crosswinds. Block in at the proper gate, exactly on centerline and stopped within 2 inches of the stop line and the GPS tells me I’m 3 feet off course. Thank you, you electronic nagging Ferdinand Magellan, go talk to the spinning down INS gyroscope.

You think that’s a bad flight? I can top that - ATL-SYD. On Delta. In coach! ???

To be fair, you guys have those dudes marshaling you into the gate. And don’t you also have a camera on the nose gear to ensure you hit the lines? ?

Inertial navigation is pretty cool. Very helpful when other aides aren’t available.

You forgot about (or maybe didn’t know of) the rollover error every 19 years or so. The field holding the date counts up, then rolls over to 0 and starts over. If your receiver isn’t smart enough, it’ll timestamp things wrong, like the photos you took on vacation at the Grand Canyon. Not that I’d have any sort of personal knowledge of that happening. ?

GPS Roll Over

Of course the next GPS rollover is supposed to happen in 2038. 2038 also happens to the the Unix rollover year as well. People may want to avoid embedded systems in 2038 ???

You may want to review the technical information about CarPlay that I posted the link to earlier.

I did which is why I think that link doesn’t make any sense. How come recalibrating the gps with the phone fixes it if it’s controlled by the cars gps? My other theory is 17.2 is suppose to fix the WiFi issues. I wonder if CarPlay is losing synch with the phone since it uses WiFi to connect to it.

Cockpits are small, get up to stretch? Yeah good luck with the three steps you can take (but only if they’re small ones) before hitting the cockpit door.

ATL- SYD in coach is … hell on earth.

Modern INS’s are quite accurate, when combined with GPS it’s an amazingly accurate navigation suite. You hear this Bill Ford? We need this! Who cares about a new MSRP in the mid 6 figures!

The B-777 has cameras . The aircraft I flew most of m career does not (MD-11). The marshallers always made me think of the movie Airplane! A very high percentage of gates now have an automated system for getting us in. It’s ummm … ok.

I would also bet that the aircraft you were/are flying, and definitely not an MME or iPhone, had/has some sort of differential GPS or a WAAS in their nav system. It was one of those up and coming things when I was working with the GPS stuff, but as life often does, mine went off in a different direction.

DGPS and WAAS

Anyone find an app to see what GPS system the phone is using? I'm wondering if it' bouncing back and forth between them rather than losing lock. Hell my drones only need 4 locks to be pretty freaking decent.

Don’t give me the “cockpits are small” line ? I’ve seen the secret bedrooms you guys get in the “attic” ? Actually, as I recall, on Delta’s MD-11s, after takeoff, the closed off an area by 1L with folding partitions into what I believe was a bunk for the pilots.

FAR mandated for flights scheduled for more than 12 hours. It’s quite literally bunk beds and coffin sized. Literally. Better not be claustrophobic (which I tend to be).

17.2 beta hasn’t helped

So, better than coach ?

I think right around the last 2 versions of IOS16 they really started screwing with the GPS. Mine would freak out on my 12. 'Fast forward' to the 15 and it's always been wonky.

I was able to find an app to pull the GPS data and it'd randomly say i was doing .48mph in some direction and the GPS 'clarity' was between 14 and 140 horizontally. Vertical was always .16ft. It'd go through periods of 'better' but it was moving every second.

What app did you find that can do this?

Did someone say “coffin-sized”? May I introduce Upper Class on the Virgin Atlantic A330-300 ?
By the way, I do not resent crew rests in the least. I much prefer well-rested and refreshed cockpit and cabin crews ? and their rest areas should be true rest areas - separate from passenger spaces. I’m actually more interested in the various creative solutions designers come up with for them.
