Accomplishments of Industry Partnership

As has already been stated, traditionally, ISRO forged a strong relationship with a large number of industrial enterprises, both in public and private sector to implement its space projects. This strategy has resulted in diffusing the state of art technologies, which are developed for the space projects into Indian industry. Close to one third of ISRO’s budget flows into industry for supply of various products and services. ISRO’s industry participation policy emphasises that ISRO will realise higher levels of aggregates for hardware, software, systems and services from industry and will desist in investing in production facilities in house.

In accordance with ISRO policy of maximal utilisation of industry capability, thrust was accorded resulting in the identification of several new industries for placement of orders and work related to spacecrafts, launch vehicle and ground segment, which have grown both in terms of complexity and scale. Indian industries continue to support all important space projects – PSLV, GSLV, IRS and INSAT.


GSLV-MKIII

In the launch vehicles arena, major hardware realised by the Indian industries include VIKAS engines for powering the liquid propellant stages of PSLVs/GSLVs, propellant tanks, toroidal water tanks, Cryo engine fabrication, tanks and structures for cryo engine programme, internal subassemblies and interface elements, feed lines, Remote Fill and Drain System (RFDS) tubes, metallic bellows , flexible hoses etc., Capability of industry is also being utilised for fabrication, assembly and testing of a variety of pressure transducers and temperature sensors for launch vehicle applications.

The requirements of metallic rings, forgings, castings and other specialised materials required for the huge solid propellant boosters of PSLVs/GSLVs is also met by the Indian industry. Further, ISRO has developed through Indian Industry a Lin shielded liquid hydrogen tank to meet the large storage requirement. Test facility augmentation for C25 stage is currently under progress with the participation of industry. To meet the requirements of launch vehicles for future missions, ISRO is continuously augmenting the facilities at industry and developing new vendors.

The infrastructure required for the production of solid propellant and processing huge solid boosters, integration of launch vehicle stages, launching pads along with the associated facilities, etc., have all been realized with the active participation of big & small, public and private industries.

In the spacecraft area also, for meeting the demands of increasing number of projects, ISRO has embarked on outsourcing of its production activities in a big way. Over the years, vendor base for fabrication and testing of specialised subsystems have been developed. Avionics Production Group in ISRO Satellite Centre has been serving as a single window for fabrication, testing and delivery of electronic subsystems.

Fabrication of solar panels, propellant tanks, Reaction Control Thruster (RCT) injectors, DC Torque Motors, production of heat pipes, fabrication of mechanism elements, battery fabrication, supply of core power packages, shunt packages, EED packages, TCXOs, fabrication of TTMC packages, supply of transponder elements, MMICs, manufacture of OSRs, fabrication of spacecraft structure, etc. include the long list of contributions made by the Indian industry to the satellite program. More than 200 packages consisting of DC-DC converters, core power packages, sheet power package, telemetry and telecommand package, EMI filters and AOCE and BMU packages were also delivered by industry.
