HeidelSat [Uni. Heidelberg]

The HeidelSat, (Heidelberg Satellit) is a pico-satellite student project at the SRH University, Heidelberg based on the 1U CubeSat standard.

Heidelsatís mission is to measure the cosmic rays with energies of about 1 GeV and to investigate possible correlations with meteorological data to find out whether the intensity of the cosmic rays has an influence on the climate on earth. It is designed for a polar low earth orbit (LEO) of about 500 km. The experiment on the satellite is to measure cosmic rays during two years.

A standard CubeSat design with solar cells on each side would not be able to provide the needed power for HeidelSat. For this reason the team propose a new mechanical concept, used for HeidelSat. This new concept contains eight deployable panels with two additional solar cells on each side. With this new structure the generated power, is even without an altitude control, sufficient to provide enough power for HeidelSat in the sun and the shadow phase.

The project is slowly ongoing, with no launch date set.
