The small-scale magnetospheric and ionospheric plasma experiment (SNIPE) is a
mission initiated by the Korea Astronomy and Space Science Institute (KASI) in 2017 and
comprises four 6U-sized nano-satellites (Korea Astronomy and Space Science Institute
Satellite-1, KASISat-1) flying in formations. The main goal of the SNIPE mission is to
investigate the space environment in low Earth orbit at 500-km. Because Iridium &
GPS Board (IGB) is installed on the KASISat-1, a communication simulation is required to
analyze the contact number and the duration. In this study, communication simulations
between the Iridium satellite network and KASISat-1 are performed using STK Pro (System
Tool Kit Pro Ver 11.2) from the AGI (Analytical Graphics, Inc.). The contact number and
durations were analyzed by each orbit and date. The analysis shows that the average
access number per day is 38.714 times, with an average of 2.533 times per orbit for a
week. Furthermore, on average, the Iridium satellite communication is linked for 70.597
min daily. Moreover, 4.625 min is the average duration of an individual orbit.
