ISRO Inertial Systems Unit (IISU), Thiruvananthapuram

The ISRO Inertial Systems Unit (IISU), Thiruvananthapuram is responsible for the design and development of inertial systems for launch vehicles and spacecraft programmes of ISRO. Major systems like Inertial Navigation Systems based on mechanical gyros and optical gyros, Attitude Reference Systems, Rate Gyro Packages and Accelerometer Packages are developed indigenously and used in various missions of ISRO. The IISU also designs and develops actuators and mechanisms for spacecraft and allied applications. The IISU is engaged in continuous R&D too and the experience and knowledge gained over the years are used for perfecting the present class of sensors and systems and developing new technologies. Further, IISU has also initiated advanced technology development programs in niche areas to adapt itself as a Centre of Excellence in Inertial Sensors and Systems. The IISU strives to make the systems cost effective, reliable and realisable in tune with global trends.
