Satellite Integration and Test Center

  • The satellite integration and 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.

    • Orbit Environment Test Lab

      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 launch vehicle 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.

    • Electromagnetic Wave Environment Test Lab

      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.

    • Launch Environment Test Lab

      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.

    • Assembly and Precision Alignment Test Lab

      This lab is used to check the assembly of a satellite and measure the alignment of the sensors installed in the satellite. The clean facility can maintain 10,000 class or better cleanliness. It is equipped with an alignment measurement system to measure and verify the accuracy of assembly of ultra-precision parts, a 3D location measurement system, a cleanness measurement system, a PFO (Particle Fall-Out) photometer to measure surface particulate contamination, an IR spectroscope to measure and analyze surface-adsorbed molecular contamination, a visible ray-UV spectroscope to measure the transmissivity of each wavelength of optical parts, and an IR lamp to check for contamination of a satellite’s surface.
