After the initial success of MASAT-1, a new pocketqube class satellite is being developed in the Budapest University of Technology and Economics. Its aim is to be developed by only students and tutors. The forthcoming satellite, Smog-1, according to its name, is supposed to be monitoring the space for the electrosmog we emit. Our range of interest is the digital terrestrial video broadcast and amateur band. The pocketqube standard is 5x5x5 cm instead of the 10x10x10 cm cubesat standard, so the usable surface area is one fourth, the volume one eighth of the initial MASAT-1, stating a great challenge. According to the foreseeable future, our launch will take place in 2017.

The aim of this thesis is to support the environmental tests during the development. Devices going into space have to comply numeral test, starting with the rocket's vibration spectrum through evaporation to extreme temperatures. During the tests the satellite will be placed in a vibration bench, thermal chamber, vacuum chamber and thermal-vacuum chamber. Vital analogue and digital signals, the temperatures of the solar cells and dissipating chips have to be constantly monitored. The task consists of designing the hardware, writing the processing software, archiving and validating. The project utilizes only open-source or freeware softwares hence demonstrating that there is no need demanding or expensive equipment in the educational satellite development.
