Project description and goals[edit]

PROITERES (Project of OIT Electric-Rocket-Engine Onboard Small Space Ship) or 大阪工業大学 電気推進ロケットエンジン搭載小型スペースシッププロジェクト in Japanese is a satellite launched by ISRO in 2012 for Osaka Institute of Technology(OIT). This small (15 kg) boxlike system, with solar panel on hull, is the testbench for the 4.4 W Pulsed Plasma Thruster[1] operating on the microsatellite platform. Total power budget of satellite is 15 watt. Also, secondary goals were stated by manufacturer:[2]

  • Experiments of two-way radio signal propagation characteristics using amateur radio (430 MHz) band.
  • Communication tests of satellite communication technology using off-the-shelf consumer-grade components.
  • Tracking and communicating by radio amateur around the world.
  • Monitoring with a high-resolution camera the Yodogawa basin near Osaka and other parts of Kansai District

It is equipped with 3-axis magnetic torquers and gyro-sensors for attitude control, magnetic sensor on boom, solar sensor and CMOS camera.[3]


As in 2013, PROITERES does not respond to any ground commands, although still broadcasting telemetry data. According to PROITERES development team report 17 January 2014 at JAXA annual symposium, the PROITERES had a design error resulting in flight computer boot loop. The root cause of the boot loop was the electromagnetic compatibility issue, resulting in reset signal being generated if power-up ramp rate of flight computer is high enough. The Osaka Institute of Technology team have abandoned attempts to restore communications with PROITERES satellite and proceeds with the PROITERES-2 design.
