Aoba Velox-III is the first satellite jointly developed by Nanyang Technological University (NTU, in Singapore) and Kyushu Institute of Technology (“Kyutech”, in Japan).
Besides educational objective, the satellite is used to demonstrate the operation of PPT for attitude control and orbit maintenance, wireless communication of OBDH subsystem and evaluate radiation effect on commercial off-the-shelf microprocessors in space.
This satellite was launched by Kounotori-6 (HTV6) on 9th December 2016, and will be deployed from the International Space Station (ISS) on 16 January 2017.
• Demonstration of Pulsed Plasma Thruster（PPT）on orbit for attitude control and orbit maintenance.
• Evaluate radiation effect on commercial off-the-shelf microprocessors in space.
• Implement a 2.4 GHz wireless communication for OBDH subsystem.
• Establishment of fundamentals of a satellite project conducted by Kyutech undergraduate students.
