[Nuriho 3rd Launch] Chasohyeong 2nd Mission Successfully Underway

On the 26th, the Ministry of Science and ICT announced that it successfully established two-way communication with the Next-Generation Small Satellite 2 (Chasohyeong 2), which was launched aboard the Nuri rocket's third launch vehicle at 6:24 PM the previous day.

Chasohyeong 2 first received satellite signals at the King Sejong Station in Antarctica 43 minutes after the launch the previous day. Additionally, around 7:58 PM on the same day, initial communication was successfully established through the Daejeon ground station, and seven more communications were completed through Daejeon and overseas ground stations by early morning.

During these communications, checks were performed on the satellite’s remote meter reading information reception, normal sun-pointing attitude status, communication system transmission and reception functions, command and data processing system functions, and power system solar panel power generation functions, all of which were confirmed to be normal.

The operator, Korea Advanced Institute of Science and Technology (KAIST), plans to continue monitoring the satellite’s status for the next seven days while deploying the Synthetic Aperture Radar (SAR) antenna and stabilizing its attitude. Over the next three months, initial operations will be conducted to inspect the payload and prepare for mission execution. Subsequently, the satellite will commence full-scale mission activities, orbiting the Earth approximately 15 times a day in a sun-synchronous orbit for the next two years.

Meanwhile, the Korea Astronomy and Space Science Institute (KASI) is sequentially attempting communication with the four CubeSats named ‘Doyosat.’ The first satellite (Garam) received satellite signals around 8:03 PM the previous day, and the second satellite (Narae) performed satellite signal reception and two-way communication around 6:40 AM on the same day. For the third (Dasol) and fourth (Raon) Doyosats, continuous attempts to receive satellite signals and communicate with the satellites will be made going forward.

Among the three industrial CubeSats, two have confirmed their positions through satellite signal reception (LUMIR-T1 at 7:53 PM the previous day and KSAT3U at 11:07 PM the previous day). Continuous attempts to receive signals and communicate will also be made for the remaining satellite.

Cho Seonhak, Director of the Large Public Research Policy Division at the Ministry of Science and ICT, stated, “Communication with the ground station for Next-Generation Small Satellite 2 has been successful, and we will do our best to ensure that communication and mission execution for the remaining satellites proceed smoothly.”
