Nuri’s performance verification satellite succeeds in communicating with the ground station… “in normal operation”

“Activating the GPS receiver with a remote command”
Received verification of payload orbital insertion capability… Cube satellite to be launched from 29th

Two-way communication between the performance verification satellite and the ground station separated from the Korean launch vehicle Nuri (KSLV-II), launched on the 21st, was successful. It means that the satellite can send and receive command signals, which means that the satellite is functioning normally.

The Ministry of Science and ICT announced that at around 3:02 am on the 22nd, two-way communication was successful between the ground station of the Daejeon Yuseong Korea Aerospace Research Institute and the performance verification satellite separated from the Nuri-ho in the afternoon of the previous day. Nuri was launched from the Naro Space Center in Goheung, Jeollanam-do around 4 pm on the 21st, and in 15 minutes and 45 seconds, the performance verification satellite was placed 700 km in the sky.

The first communication was made with Sejong Base in Antarctica 42 minutes after launch, and with Daejeon Air Force Base 1 hour and 40 minutes later. In this case, the basic status information of the satellite was checked by receiving the signal from the performance verification satellite. In the morning of the 22nd, 11 hours later, in the communication with the Daejeon ground station, there was even a two-way communication in which command data was exchanged. As a result of analyzing detailed information about the satellite status received from the performance verification satellite, the anti-accidental research team confirmed that the performance verification satellite was in good condition and that all functions were operating normally.

As the normal operation of the performance verification satellite was confirmed, it is analyzed that the ability of the Nuri to put the payload into orbit has been verified. The Ministry of Science and ICT said, “Through two-way communication, we have activated the GPS receiver mounted on the performance verification satellite with a remote command.”

From the 29th of this month, when the orbital stabilization of the performance verification satellite is completed, the anti-corruption service will send out the cube satellites listed on the performance verification satellite in turn.
