The space test center is a cutting-edge facility for analyzing and testing the final assembly, alignment, heat/vacuum properties and electromagnetic wave properties of systems such as satellites and launch vehicles that require a high degree of reliability.
The building was constructed in 1996 and has been operated as an international certification testing agency (KT-236) since 2004.
Constructed on a 25,970㎡ site, i.e. 4 times the size of a soccer field, the center comprises an orbit environment test lab, a launch environment test lab, an electromagnetic wave environment test lab, a sound chamber, an optical payload test lab, and a precision alignment and assembly lab.
This lab is used to perform satellite assembly and precise alignment measurement of satellite mounted sensor. It is equipped with an alignment system for measuring and verifying assembly of ultra-precision parts, a three-dimensional position measurement system, cleanliness measurement equipment, PFO(Particle Fall-Out) photometer for surface particle contamination measurement, visible light-ultraviolet spectroscopes, and ultraviolet lamps for measuring the transmittance by wavelength of optical components.
This lab is used to conduct environmental testing of vibration, impact and sound load applied during satellite launch. It is equipped with a satellite mass measurement system, a free fall and pyro impact test system, and a structure mode test instrumentation/analysis system.
The lab simulates a high vacuum of less than one billionth atmosphere and extremely high/low temperature environments under which a satellite operates. It conducts tests to check that the satellite system and parts and the projectile function correctly in the space environment. It is equipped with a large thermal vacuum chamber with a diameter of 8m and length of 10m developed in Korea, a small to medium-size thermal vacuum chamber, a thermal cycle chamber, a thermal impact chamber, and a backout chamber for removing ground pollutants.
Satellites are exposed to electromagnetic waves throughout the entire cycle from launch site to launch process, and operating environments in space.
This lab is used to conduct suitability tests of the radiative and conductive electromagnetic wave noise environment. It is equipped with a DC~40GHz frequency band measurement system and a 200V/m electric field generation system.
In satellite development, it is essential to verify the electrical and software design before final assembly of the flight model and start of the test.
It is the facility that developes and tests ETB(Electrical Test Bed) for this purpose.
The electrical test system consists of electrical equipments or simulators that have the same function as satellites that will perform functions in real space, and the mechanical shape is different from the flight model.
The electrical test equipment is connected to the electrical ground support equipment for testing and verifies its performs using the commands used for actual satellite operation. The facility is equipped with electrical ground support equipment and instruments capable of signal measurement.
