Here is an example of pretty stunning amount of visual detail provided by one of popular GPS data app on Android: https://play-lh.googleusercontent.com/lT3TpHarUx89Z7HIf043aU... At least I can confirm it works will all navigation constellations on Samsung S10.

I had a lot of fun with that gps status app when I first got a smart phone - you could hold your phone up to the window while flying (to get gps signal) and see the 630mph or whatever speed you were going.

I do this with google maps even without an internet connection it shows roughly where we are in the US on a flight

I thought this was disabled above certain speeds to prevent those chips being used in Missiles?

For the limits the speed is 1200 mph and the altitude 59,000 ft.

A commercial airliner won’t exceed 650 mph or 40,000 ft.

I think those are the old COCOM limits which are no longer in effect. I believe that currently the only limit is 600 m/s (which is nice, since when there were both speed and altitude limits some manufacturers OR'd them and some manufacturers AND'd them, so it wasn't clear if altitude alone would be enough to disable a device until you found out the hard way)

Ah, yeah that's been updated since I've worked with GPS

This looks a lot like "GPS Status" and it used to be really good. Recent comments on the Play Store do not sound good though.

It used to be, but a lot of data got pay/subscription walled I think.

I would recommend GPS Test, it's open source, no ads and does just as much.

Yea GPS Test is great!

Link doesn't work for me and the URL is obscured for some reason. Is my guess correct that you're linking the GPSTest app?

Yeah, its the "all sensor data at a glance page" https://play.google.com/store/apps/details?id=com.eclipsim.g...

No, it's not GPSTest but "GPS Status & Toolbox".
