VIPER REXUS

Electronics & Software

The Electronics need to withstand the harsh environment of a rocket launch from ground to launch phase to near-space vacuum. Since the VIPER Experiment requires a special set of functions provided by PCBs inside very limited space, we needed to design our own.

Requirements

Hardware

  • Our biggest challenge is the environment our experiment will be executed in. With temperatures around  -80°C and almost no pressure we have to choose our parts carefully.
  • We have to make sure to deliver reliable measurement data, even in challenging conditions.
  • All ice temperature data will be measured by 27 highly accurate temperature sensors, one pressure sensor and there will be one capable of recording infrared and one able to record high dynamic range monochrome video.
  • We need batteries to power the heat probes, which in total consume around 200W over a span of 110 seconds.
  • A spindle drive should drive the HPPM precisely using an encoder and an endswitch.
  • As per the structural requirement to seal off the wet area of the experiment, special feedthrough PCBs need to be designed, which transmit signals between those two zones.
  • All of this needs to be fit into the smallest forms possible.

Software

  • The experiment needs to be controlled by our own software. For that we are able to use the signals given by the REXUS module to define destinctive points for our experiment.
  • The system needs to function without human interaction, meaning that the whole experiment procedure
  • Also the data has to be collected and stored properly. We will transmit and store our video data on our Raspberry Pi 3 using its flash storage.
  • Furthermore we want to display data currently captured on our ground station. That way we will be able to have a first glance on the results of our project.
