Cute-1.7 + APD Laboratory for Space Systems

Cute-1.7 + APD Project

Small Satellite Project (SSP), Laboratory for Space Systems (LSS), Tokyo Institute of Technology

Cute-1.7+APD is the successor of the Cute-1 nano-satellite, developped 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 20cmx10cmx10cm nano-satellite was also developped by the Tokyo Institute of Technology Kawaii Laboratory.

"Cute-1.7+APD"-#1 is scheduled for placement into orbit as a subpayload of the JAXA M-V-#8 Rocket in february 2006. The separation mechanism for release in orbit was also developped at the Tokyo Institute of Technology Matunaga Laboratory for Space System. It is based on the TSD(Tokyo-Tech Separation System Demonstration) experiment regarding CUTE-1.

Cute-1.7 + APD project is a satellite development project mainly by students at Laboratory for Space Systems, Tokyo Institute of Technology.
To launch our satellite in 2006, the project has started in January, 2004. Our satellite, named Cute-1.7 + APD, will be 200mm x 100mm x 100mm in size.

Cute-1.7 + APD will be the second satellite made in Tokyo Institute of Technology after the first one, CUTE-I, was launched in June, 2003.
This project is based on the international CubeSat project.

Cute-1.7 + APD will be launched as a sub-payload on the 3rd stage of Japanese solid rocket M-V-8 on Feb. 18, 2006. Main satellite is ASTRO-F.
The planned orbit of "Cute-1.7 + APD " is 250-280km in perigee height and 750km in apogee height, so lifetime of "Cute-1.7 + APD " is estimated much less than one year for the shortest due to atmospheric reentry. The exact lifetime is dependent on the actual rocket flight condition and atmospheric density.

"Cute-1.7 + APD II" is a follow-on satellite to the "Cute-1.7 + APD," and much improvements will be conducted in many components of "Cute-1.7 + APD II", in particular, for amateur communications system, camera system, APD sensor and so on, based on the experiences acquired in the development and operation of "Cute-1.7 + APD."

The launch of "Cute-1.7 + APD II" is planned to 2006Q3.

The web site will be updated as progress is made on the development of this project.
