Ministry of Science and ICT to Verify Attitude Control Capability During Orbit Insertion from 4th to 7th
[Asia Economy Reporter Kim Bong-su] The development of the performance verification satellite to be loaded on the Nuri rocket, which will be test-launched for the second time in June, has been completed, and the final test will be conducted.
The Ministry of Science and ICT announced on the 3rd that from the 4th for four days, a performance test will be conducted on the Cube satellites, which are performance verification satellites jointly developed by four domestic universities, to be loaded on the Nuri rocket.
The performance verification satellite will carry four Cube satellites developed by domestic universities along with the payload. It will perform missions for two years in a sun-synchronous orbit at an altitude between 600 and 800 km. The total weight is 180 kg. It is equipped with domestically developed thermal batteries, control moment gyroscopes, and S-band antennas to verify whether the payload operates according to design in the space environment.
The four Cube satellites were developed over about two years by students from four domestic universities: Chosun University, Seoul National University, Yonsei University, and KAIST. The missions of the Cube satellites include Earth observation GPS RO (Radio Occultation) data collection, fine dust monitoring, hyperspectral camera Earth observation, and multi-band Earth observation using electro-optical, mid-infrared, and long-infrared bands.
The test conducted until the 7th is a mass characteristic measurement test, and for the first time during the development process of the performance verification satellite, the test is conducted with the completed form equipped with the four Cube satellites. It performs precise measurements of the satellite body's center of mass and moment of inertia to verify whether the performance verification satellite can stably control its attitude in orbit after separation from the Nuri rocket.
Kwon Hyun-jun, Director of the Large-scale Public Research Policy Division at the Ministry of Science and ICT, said, "In the second launch of the Nuri rocket, an experiment will be conducted to actually load a satellite and deploy it into orbit," adding, "The loading of this performance verification satellite is significant as it is the first attempt to place a satellite into orbit using a domestically developed launch vehicle."
