CUTE 1 (CO 55, CubeSat-OSCAR 55)


The CUTE 1 (Cubical TITech Engineering Satellite) will conduct the following three missions.

  • Communication Mission
    - Continuous transmission of CW-Telemetry by CW-transmitter (As a beacon)
    - Transmittion of FM-Telemetry including payload data by two different protocols
      - Ax.25 protocol
      - SRLL(Simple Radio Link Layer) protocol
    - Change the two communication protocols by uplink command from ground station
    Sensing Mission
    CUTE-I has some various sensors: thermometers, accelerometers, gyros and sun sensor, and so on. Measuring temperature, acceleration, and angular velocity of CUTE-I on orbit, we will obtain the satellite condition data in space environment.
  • Deployment Mission
    CUTE-I has a deployable solar cell paddle that can be deployed by a command uplink to verify whether or not the deployment mechanism operate well in the space.

CUTE 1.7 is a follow-on model to precede the more sophisticated CUTE 2.
