Physical Research LaboratoryPhysical Research Laboratory (PRL) at Ahmedabad, is an autonomous institution supported mainly by DOS. It is a premier institute engaged in basic research in experimental and theoretical physics, astronomy and astrophysics, earth, planetary and atmospheric sciences. The activities cover a wide spectrum of competitive research in all these areas. PRL is also involved in conducting extensive academic programmes for Doctoral and Post Doctoral research and also has an Associateship programme for university teachers. It is also entrusted with the management of the Udaipur Solar Observatory (USO).ISRO Inertial Systems Unit ISRO Inertial Systems Unit (IISU) at Thiruvananthapuram has been the center of excellence in the area of inertial systems for launch vehicles and spacecrafts. IISU carries out research and development in the area of inertial sensors & systems and allied satellite elements. It has facilities for precision fabrication, assembly, clean room and integration and testing. This unit has the total capability to design, engineer, develop, qualify and deliver inertial systems for the entire Indian Space programme.Space Applications Centre design and development of payloads, societal applications, capacity building and space sciences, thereby creating a synergy of technology, science and applications. The Centre is responsible for the development, realisation and qualification of communication, navigation, earth & planetary observation, meteorological payloads and related data processing and ground systems

Liquid Propulsion Systems CentreThe centre located at Bangalore is responsible for Satellite Propulsion Systems Integration for GEOSAT and IRS programmes. The centre is also responsible for design and development of monopropellant propulsion system, System engineering, Transducer and Spacecraft propellant tanks. The centre is involved in R&D and TDP activities towards development of electric propulsion system, propellant gauging system for spacecraft, advanced transducers etc.Satish Dhawan Space CentreSDSC SHAR has the necessary infrastructure for launching satellite into low earth orbit, polar orbit and geostationary transfer orbit. The launch complexes provide complete support for vehicle assembly, fuelling, checkout and launch operations. Apart form these, it has facilities for launching sounding rockets meant for studying the earths atmosphere.ISRO Satellite CentreISAC at Bangalore is engaged in developing satellite technology and implementation of satellite systems for scientific, technological and application missions. ISAC is functionally organised into five major areas: mechanical systems area including structures, thermal systems and spacecraft mechanisms; digital and communications area including digital systems and communication systems; integration and power area comprising spacecraft checkout, systems integration and power systems; controls and mission area consisting of control system, mission development and computer and information; and facilities
