Will Payload Tracker work with it? (I'm planning on doing a high altitude launch myself) I have a TNC, a TinyTrak3+. Will Payload Tracker work with it?

They are only required to stop operating above 60k feet when also above 1000Mph. JonM, Cool balloon project :) hope you find out what went wrong.

But it is close enough to the limit that I would still be suspicious. Oops, I am dyslexic. 56092 vs 59062. But it is close enough to the limit that I would still be suspicious.

I would love to be involved in it if I was around your location. 59,062 feet sounds suspiciously close to the 60K feet legal limit for GPS. In fact, it is almost exactly 18,000 meters which is the number most manufacturers use for the limit. Civilian units are supposed to stop reporting above that height (though some are lax about implementation) - units that function above that are restricted material. If GPS was the only way you were receiving coordinate data, it's possible the GPS module stopped updating its position because it was over the limit, and simply repeated the last known legal coordinates.
