Title: The design and the performance of stratospheric mission in the search for the Schumann resonances,
Abstract: The technical details of a balloon stratospheric mission that is aimed at
measuring the Schumann resonances are described. The gondola is designed
specifically for the measuring of faint effects of ELF (Extremely Low Frequency
electromagnetic waves) phenomena. The prototype met the design requirements.
The ELF measuring system worked properly for entire mission; however, the level
of signal amplification that was chosen taking into account ground-level
measurements was too high. Movement of the gondola in the Earth magnetic field
induced the signal in the antenna that saturated the measuring system. This
effect will be taken into account in the planning of future missions. A large
telemetry dataset was gathered during the experiment and is currently under
processing. The payload consists also of biological material as well as
electronic equipment that was tested under extreme conditions.
