Hi,
Anyone running in the problem of not having altitude readout with the iPhone X?‌  We've tested on 3 brandnew phones, all no luck. My previous iPhone 6s worked flawless. Some other apps also don't seem to display altitude when SD is active. When using external BT GPS it's working fine..

A‌nyone have a clue?

R‌egards, Dennis‌‌

I have the same problem with my iPhone 7plus. No altitude  indication and sometimes it stopped logging due to poor GPS signal. It happens only in the air. As soon as I am on the ground (but still in the plane with running engine) GPS signal is good. It looks that when I switch to airplane mode, GPS signal is slightly better. With my previous iPhone 6 I always had perfect GPS signal with altitude indication.

My iPhone 7 running iOS 11.2.6 on SkyDemon version 3.9.109 has also issues indicating altitude. It also stops sometimes logging the flight and resumes when the GPS signal is working again.

I’ve used iPhone for air navigation for several years now. (Skydemon, Air Nav pro, easyvfr basic). No problem on any iOS device. Until now. Bought an iPhone X. Problem, it shows the lat-long position, but NO altitude. Tried it on three iPhone X’s (also Dennis’s iPhone) All the same problem, with all kinds of altitude apps.

Contacted Apple. Senior engineers now say that the gps is not for active tracking. I was really angry and confused. Could not believe their answer. Have now done additional diagnostics. Contact appointment for tomorrow to read out my iPhone X and 5s.

Have also contacted PocketFMS to ask if they have experienced problems. They will now contact Apple trough their developers to find out more.

As it seems at the moment all air navigation apps are then obsolete for iPhone X users.

Can Skydemon maybe also contact Apple development for enquiries?

Does anyone use Foreflight to test and maybe get them to contact Apple?


Hope to hear from you soon.

IPhones are consumer devices. My understanding is that the internal GPS antenna is weak and that it relies on wifi source triangulation to improve it's fixes or the Telephone network (found that on the web). Once you leave the cell of your telephone network your fix is lost.You are better off with a more reliable GPS source: The best is bluetooth GPS . https://bad-elf.com/collections/bluetooth-gps
