Cute-1.7 + APD II is the successor of the CUTE-I nano-satellite and Cute-1.7 + APD developed and built by the second generation of students of the Tokyo Institute of Technology Matunaga Laboratory for Space System (LSS). The Avalanche Photo Diode sensor module, or APD, embarked on this 20cm x 15cm x 10cm nano-satellite was also developed by the Tokyo Institute of Technology Kawai Laboratory.

Cute 1.7 + APD II is an amateur satellite which uses amateur band frequencies . We would like to take this opportunity to thank the Japan Amateur Radio League (JARL) and the Japan AMSAT Association for their guide concerning the development of the satellite . And we appreceiate Mr.Hans van de Groenendaal(ZS6AKV), IARU Satellite Adviser, who helped us greatly in frequency coordination.

[edit] About Subsystem

A satellite is composed of many different subsystems which all have a specific function. The EPS subsystem, which handles the regulation of internal power or the Communication subsystem, which handles the receiving and sending of data by the satellite, are two examples of the many sub-systems that compose a satellite.

Here is the list of the subsystems :

  • C&DH (Command & Data Handling): Corresponding to the central computer of the satellite, it is in charge of many tasks such as orbit related calculation and data processing.
  • Communication: In charge of enable radio link communications between the ground station and the satellite
  • EPS: In charge of the satellite's power system, including batteries and solar cells
  • ADCS: In charge of the satellite's attitude control as to be able to give any free position to the satellite
  • Structure: In charge of the construction of the satellite's main structure.
  • Camera: In charge of the development and implementation of the onboard camera
  • APD: This sensor module subsystem was developed by a specific physics laboratory of this university
  • Environment: As for the orbit and control of the satellite to be smooth, this subsystem studies and models the external conditions the satellite is confronted to.
  • Separation: In charge of the separation mechanism of the Satellite from the launcher rocket.
  • Ground Station: In charge of developping the system to control the satellite from the control and operation center.
