In this video I show what tools are needed to locate a metrological radiosonde or weather balloon. These include decoders that can decode the position of the radiosondes and platforms that can calculate a good landing prediction. In addition, I tell a lot about the technical structure of the radiosonde (Vaisala RS41 & RS92) itself, as well as to balloon and parachute. There is also a community of probe hunters and databases where the found probes are logged. On the AEQ-WEB blog there is a description and links to the featured trackers, tools, decoders and communities: https://www.aeq-web.com/linkliste-radiosonden-tools-und-webseiten/ Tags: #radiosonde #Vaisala #probehunter
