Universities usually experience decreased activity. Most of our team also took the opportunity to recharge the batteries. However, some things were developed in the past week.
The team around Connor (Brian, Jens, Max, Rishi) finalized the design of the housing. The top of the building includes a grid to increase the surface area and the dissipation of thermal energy. This is the best way to protect your device from the sun. A first 3D print the LimeSDR fits into the housing. The flight models have been ordered to arrive at the end of September.
Tim and Aby worked on the software for MarconISSta. Aby managed to install all required software packages and tools on a security hardened OS provided by ESA. Tim then modified a tool called ” RX Power ” (based on rtl_power). First tests show that the system is functional. The software is now being enhanced to improve measurements and vizualization.
Now the hardware list is finalized. Jitendra and Brian worked on the verification plan. (EMC) tests are performed on the basis of the EMC test.
If you want to start with to experiment to the ISS, many questions have to be answered:
- Which items will be uploaded (aka launched) to the ISS?
- How should they be labeled?
- Are there any safety issues?
- How much time do astronauts need to install the experiment?
- How much time is required to conduct the experiment?
- When should the experiment be started and how?
Martin works on these issues with partners and advisors from ESA, DLR, ARISS, Airbus, Raspberry Pi Foundation and BioTESC.
