Many manufacturers accomplished this by restricting operation when either condition was sensed, but you could find some that could be used in applications that only violated one condition, like high-altitude balloons.

- fnj 10y agoCommercial jetliners never fly at 18,000 m (nor at 515 m/s). Max is about 11,000 m or so, and about 250 m/s. It would be interesting to know if consumer GPS ever worked aboard the Concorde.
- knz 10y agoIf you're going to use the Concorde for a speed test then you might as well also test the SR-71. For..er... science!

- 13of40 10y agoA couple of years back my kid got the GPS working on his Windows phone, using some 3rd party app that cut through all of the other location detection crap. We were able to track our speed and location in a passenger jet flying out of Maui.
- anticodon 10y agoYou can use offline GPS navigation software on a plane. I did it several times, just as my friends. I use LG G3 and OsmAnd app. LG G3 has very poor GPS antenna so you have to press the phone against the plane window and wait for 4-5 minutes before it finds sufficient number of sattelites.
- 4ad 10y agoIf you take pictures from the air with an iPhone, they will be geotagged. When you land and you get internet back, they will be labeled correctly in Photos.app. Other phones had trouble finding GPS signal in airplanes, but I never had a problem with my iPhone 6s or iPhone 7.
