This article describes the software for factory-installed Meteomodem M20 radiosondes operating in the Horus V2 standard. Developed by the AMPER Student Research Group for Electronics at the University of Tarnów, this version of the program runs on a recovered meteorological probe and requires no additional modifications (e.g., microcontroller replacement). Due to severely limited resources (the original microcontroller has only 32kB of Flash memory), the Keil package was used for compilation. This commercial software is available, but for L0 series processors, the package is free; its use requires only prior registration. The software was tested in three consecutive balloon missions. In the BEM 1 mission, a probe was sent with software transmitting in the RTTY standard, while in the BEM 2 and BEM 3 missions, the software described in the article was tested operating in the Horus V2 standard.
