Study on Kompsat Satellite Mission Lifetime Factors

open access: yesJournal of Astronomy and Space Sciences, 1998
As the satellite system becomes more complex, the probability of unpredictable failures may be increased due to design inadequacy, experience deficiency, lack of problem recognition. Poor quality control, improper testing, and workmanship fault. Consequently, these problems can lead to the reduction or end of the satellite mission lifetime.
