Myself and my 11yr old son would like to send a weather balloon up to altitude of 100,000ft with a payload containing a couple of cameras. We would like to record altitude, temperature and position of balloon. Have looked at radiosonde and it seems to tick a lot of the boxes, does any one know if it is possible to track radiosonde in real time which would help with recovery of cameras and how to retrive data collected from radiosonde.
