17th March 2022 - Long Range TTN Test ? Anybodys here who nows about?

Hi Community, while watching some data on the ttnmapper.org i found out a fresh (5 days old) long-range test. Is here somebody reading this post who nows about this ? I am interested to get some more informations or details, as some of our Gateways recieved these data from > 232 km … from 4k m altitude up to 9k m altitude. Happy to hear from you ! Best regards

… some more stalking later: it seems to be a balloon that was startet in the west of Netherlands next to Gateway “c4l-hab-nl” … ttnmapper is showing a nice line on the heatmap. The track ends in 9k altitude near Gateway “2kh-ttn-gw-o-st0001” in Germany.

This is a node in an airplane.
btw: it is illegal to use a transmitting node in an airplane without the permission of the aviation authority.

Quite possibly a HAB indeed, with wind from NNWest closer to ground and at lower levels then picking up e.g. jetstream as it gets higher, though could just as easily be a node on an aircraft as Wolfgang suggests- take off to SSEast then turn onto flight path though such turns typically tighter. Carried by self-loading freight or perhaps attached to an asset or piece of cargo for tracking and condition monitoring purposes? Guess no way of knowing…unless local balloon enthusiasts mentioned the launch?

The fact there is a sudden end at altitude suggests likely a balloon burst event with fall to earth not well tracked?

Would be good if the HAB guys used ‘experiment’ option vs main data feed when posting on TTN Mapper…
