The development of our software has been under great progress. With this groundstation we can test our electronic components. This interface is as well important for our launch campain. We can see if the sensors work correct, if the Hatch opens correctly and can see all values of the temperature and pressure sensors.
Also the Microcontroller Software, written in pure ANSI-C, has done great progress. Altough there is not much more to see than blinking lights at this point, you can see the development using the IDE (CoIDE) for the Microcontroller we choose, an STM32F103 with 72 MHz.
Of course it is necessary to simulate the environment to adjust the experiment parameters. A simulation using SimuLink has been performed to analyze the heat loss of the sensors during flight to determine the correct control parameters. We will most likely use a PID control.

Weekly Teammeeting at the University Library. At our first group discussion after the CDR we improved our design and Student Experiment Document (SED) with the helpful critics of the review comitee. The review comitee consistes of experts from DLR, ESA, SSA and ESRANGE that helps the students to develop the experiment.
We discussed a timetable and the work order for electronics and mechanical parts. In addition we introduced our new teammember Nathanael in our experiment design. Nathanael is 21 years old and studies mechanical engineering in the 4th semester. He will help the mechanical team members with the inner chamber and the electronic box.
