The testing equipment is mostly build up in our clean thermal vacuum laboratory. There we have different chambers and measurement tools running. The laboratory is also used as an area for cleaning via ultrasonic and as a place for clueing and potting under clean conditions. The chambers and the other equipment are kept clean by following our cleanliness.

STI´s Thermal Vacuum Laboratory covers:
  • Testing of function and performance parameters of spaceflight products under different pressure and temperature conditions. This can be a thermal cycling test in ambient pressure as well as under vacuum
  • Performing of bake-outs to outgas different types of structures – preparation for TV-Test
  • Measuring the outgassing behavior of distinctive types of structures
  • Cleaning and clueing area
Recent projects:
  • Coarse Earth- & Sun Sensor - CESS
  • Laser Ranging Instrument – LRI
