Proposal of Nano-satellite Environment Test Center
• Center dedicated for environment test of nano-satellites
– Carry out all the test necessary for nano-satellites or
components of 50cmx50cmx50cm、50kg
– Provide a quick test place for prototypes developed by local
industries
– One-stop-service for space environment test
Slide used at IAC 2009
Original idea of nanosatellite testing center was in 2008

To be capable of doing all the tests for a satellite up to 50cm, 50kg
Vibration
EMC & Antenna pattern
Pressure & Leak
Thermal vacuum
Assembly & Integration
Vacuum thermal shock
Thermal cycle
Shock
α&ε measurement
Outgas
(ASTM E595)
12
Mechanical testing
Vibration
Mandatory for all piggy-back
satellite
Advantage :
Quick review system based
on LabVIEW
Nominal testing time:
2.5 days for 50kg
1.5 days for 1U
Shock
Air gas gun type
Producing high level separation shock
for various launchers, H2A, Dnepr, etc..
13
Thermal testing
Target : up to 50kg, cube-sat and sub-system
Small (ø0.3m) and Large(ø1.5m)
Purpose 1:
Verification of thermal design and
operation under low and high temperature
environment.
Purpose 2:
Detection of hidden detects and
bug in the program.
It is possible to find
for long term test as 1 week
Recent update
Solar simulator
30cmx30cm area with 1400W/m2
Clean room (80m2)
Class 7 or better for integration and
functional testing
2.4m S-band (2.4GHz) antenna

Operation rate of these machines strongly depends on the H2A
piggy back program. In 2014, four H2A rockets were launched.
Half of the satellite developers using H2A piggy back rides in
2014 conducted tests at CeNT.
