Demonstrate CubeSat platform technologies including 360-degree camera.


Mission objectives:

  1. In-orbit test of the onboard computer system consisted of a Linux-based microcomputer.
  2. 360-degree Camera Unit test to take all-sky images with two fish-eye cameras.
  3. In-orbit test of newly developed attitude control system using dual reaction wheel mechanism.
  4. In-orbit test of SDR-based receiving system for 920MHz band (SDR receiver No. 1) to receive the signals from IoT devices on the Earth. The satellite and the ground station verify the received data whether the IoT devices transmitted the data successfully
  5. In-orbit test of remote sensing data reception on the seafloor crustal deformation transmitted by IoT devices connected with observation devices on the sea. The satellite and the ground station verify the received data whether the IoT devices on the sea transmitted the data successfully.
  6. Receive AFSK/GMSK packets on 435 MHz band with the onboard transceiver (RX: Software-defined Radio (SDR) receiver No. 2), and the received packets will be sent on 430 MHz band downlink. KOSEN-2 provides a packet forwarding service by the 430MHz transceiver for amateur radio operators. The 1200 BPS (AFSK on FM) and 9600 BPS (GMSK) modes are available by KOSEN-2. The amateur radio operators examine satellite communication by KOSEN-2 for self-training, intercommunication, and investigations.
