The new On Board Data Handling system is designed according to the more of 20 years of experience of Prof. Renner, TU Berlin, with the space heritage of seven TUBSAT in orbit. The design is based on the main principle KISS, Keep It Simple Smart.
The transparency of the OBDH-design enables a high reliability and stability of operation e.g. against radiation. It avoids especially unexplained phenomena observed by the operation of several TUBSAT. The OBDH process the commands from the ground station and can also operate autonomic on user defined events. The connections to the single satellites modules and to the payload are performed by Serial Communication Interfaces.
