PROITERES or Project of OIT Electric-Rocket-Engine Onboard Small Space Ship (Japanese: 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) is a satellite launched by ISRO in 2012 for Osaka Institute of Technology (OIT).

This small (15 kg) boxlike system, with solar panels on the hull, is the testbench for the 4.4 W Pulsed Plasma Thruster[1] operating on the microsatellite platform.

PROITERES' secondary goals, as stated by the manufacturer, are:[2] It is equipped with 3-axis magnetic torquers and gyro-sensors for attitude control (orientation), a magnetic sensor on the boom, a solar sensor, and the Complementary Metal Oxide Semiconductor (CMOS) visible spectrum camera with a five-lens system and a focal length of 85.3 mm and a f number of 3.6.

The root cause of the boot loop was the electromagnetic incompatibility issue, resulting in a reset signal being generated if power-up ramp rate of the flight computer is high enough.

The Osaka Institute of Technology team abandoned attempts to restore communications with PROITERES satellite and proceeded with development of the PROITERES-2 design.
