INTU ATE

Instrument Test Unit For Advanced Inertial Sensors (INTU) is used for testing and evaluation of Ring Laser Gyro (used in GSLV/PSLV launch vehicles), that detects the angular displacement during rotation. The INTU receives displacement signals from the sensor (RLG) to evaluate the sensor characteristics and also generates signals required towards initiating the action of the sensor.

This system contributes to the successful launch of many of India's rocket launch vehicles including the Polar and Geostationary Satellite Launches, the Chandrayan and the Mars Orbiter missions.

The INTU system consists of the following boards:

  • Processor module
  • INTU Interface Module
  • Light-up module
  • Current Monitoring module
  • Rear I/O module
  • Fan Failure Indication module
