CO-65 (Cube Oscar 65) CUTE 1.7+APD II

CUTE-1.7 + APD II - CO-65Cute-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.
