Space Qualification and Acceptance testing
The objective of Qualification and Acceptance testing is to identify possible design flaws during the development process by simulating the launch vehicle ground and flight environmental loads including space and upper atmosphere conditions. Testing is required for all nanosatellite components as well as the full spacecraft assembly, to ensure the spacecraft meets the performance criteria for a forthcoming mission and all applicable CubeSat standards.
Serenum as a part of VZLU group provides a complex set of design verification services, including:
- Design of custom test plans and procedures, considering spacecraft mission conditions
- Custom design and manufacture of test GSE
- Environmental testing
- Vibration and Shock testing
- Thermal Vacuum Cycling
- Radiation Hardness testing
- ISO 6 Cleanroom and ISO 8 Cleanroom available for satellite assembly and payload integration
Vibration and shock testing
Shock and vibration testing verify spacecraft performance under extreme conditions. We provide the full spectrum of mechanical testing necessary for Qualification, Proto-flight, and Acceptance of spacecraft.
- Resonance search
Thermal vacuum testing
A thermal vacuum chamber allows the simulation of conditions in space including both temperature and vacuum. The purpose of testing is to reveal possible deficiencies of the design by cycling very high and very low temperatures in a space-like environment of the chamber.
- Thermal analysis
- Thermal Vacuum Cycling
- Thermal Vacuum Bake Out
TV chamber specification:
Chamber volume: 1000 mm x 1000 mm x 1000 mm
TV tunnel chamber extension available: 10 m x 200 mm diameter
Thermal Vacuum tests are performed within ISO 6 Cleanroom.
Maximum external dimensions for parts to be placed into the chamber: 950mm x 870mm x 780mm
Vacuum value < 10-3 Pa
- Range: -120 ºC +150 ºC
- Accuracy: 0.1 ºC
- Regulated rate: 1 °C/min
The purpose of radiation testing is to verify the resistance of electronic components in an environment comparable to the natural space radiation environment. Radiation-induced damage is a common cause for early failure of many CubeSat missions, therefore thorough testing helps to ensure mission success. The testing procedures are based on the results of the radiation analyses, which verifies the full radiation field on a tested device on the selected orbit.
- Single Event Effects
- Total Ionizing Dose
- 220 MeV Protons
- Gamma 60Co
A Cleanroom is dust, temperature, and humidity controlled environment that protects satellites and spacecraft components from contamination during its development, construction, and testing. SERENUM operates class ISO 8 and ISO 6 Cleanrooms. In general, an ISO 8 room is sufficient for satellite platform assembling, while payloads usually require ISO 6 environment.
Cleanliness: ISO 8 (equivalent to FED STD 209E Class 100,000), ISO 6 (equivalent to FED STD 209E Class 1,000),
Maximum dimensions for parts to be assembled based on the room size:
- ISO 8 Cleanroom: 31,25 m2; 5,6m x 5,0m x 2,6m + 2,5m x 1,3m x 2,6m
- ISO 6 Cleanroom: 31,50 m2; 5,6m x 5,0m x 2,6m + 2,5m x 1,4m x 2,6m
