Companies building for space — satellites, launch systems, ground infrastructure — tiered by how much of the business it actually is.
PTC lists 'Space & Strategic Components' as a product category and serves launch vehicles/spacecraft with propellant tanks, propulsion nozzles, bulkheads and pump casings, indicating real but secondary space-sector exposure.
“We deliver precision-engineered components for launch vehicles and spacecraft, optimised for mass efficiency, structural resilience, and thermal resistance.”
ISROSENE is a specialty rocket propellant fuel produced by CPCL for ISRO's launch vehicle programmes, representing a niche but real supply into India's space programme.
“Speciality products - Mineral turpentine oil, Hexane, JP-5, JP-7, ISROSENE”
The company has a stated domain capability in Satellite Systems and is developing products including a Space Surveillance and Tracking Radar and a Bi-Static Radar for tracking objects in deep space.
“Robust domain capability in Radars, Electronic Warfare, Communication systems, Avionics & Satellite Systems”
ITI is accredited by ISRO's VSSC to perform component screening, testing, and assembly of space-grade flight packages.
“Accreditation of VSSC (Vikram Sarabai Space Centre, Trivandrum) for Component Screening, Test & Evaluation, Assembly & Testing of flight Packages.”
Manufactures satellite structural parts via its UK-acquired entity Chester Hall, part of Belrise's broader aerospace, defence and space platform targeting 10% of manufacturing revenues.
“Chester Hall produces precision-machined aerostructure, aero-engine and satellite components for leading global aerospace customers.”
Tata Elxsi supplies engineering services to ISRO's Gaganyaan human spaceflight programme, providing ongoing support in frontier aerospace technologies.
“Continued to extend support to Indian Space Research Organisation for the Gaganyaan mission programme.”
Space electronics is a real business segment (ISRO supplies, Space Electronics product line, ASTPL subsidiary building ASTRA SAT constellation targeting 2027-28) being demerged for sharper focus, currently smaller than defence.
“Astra Space Technologies Private Limited: A wholly owned subsidiary engaged in the design, development and integration of satellites and satellite payloads, as well as the establishment of ground stations for satellite tracking and communication.”
“The Company will bring to this nascent business (two verticals) a commitment of accelerated growth and a strong focus on supplying electronic subsystems for satellite programmes and scientific applications.”
AMS supplies indigenous payload checkout systems and other space-qualified electronics to ISRO, reflecting a real but minority line of business within its broader defence and aerospace portfolio.
“First Indigenous Payload Checkout System is supplied to ISRO, replacing Legacy Imported Systems”
“Fully Integrated Company capabilities spanning design, development, testing and scale manufacturing across missile systems, satellite and space technology, naval systems, aircraft electronics and homeland security.”
Tejas manufactures satellite ground terminals, hub equipment and Sat-IoT products for LEO/MEO/GEO connectivity as part of its product portfolio.
“Compact satellite terminals and hub equipment for LEO/MEO/GEO links, extending connectivity to rural and maritime users.”
Omnitech is pursuing space as a strategic growth vector alongside aerospace/defence, working on First Article qualifications and special-process certifications to enter space-grade supply chains.
“Aerospace, Defence and Space continue to represent a strategic growth vector, with the Company focused on converting First Article development orders into repeat production programmes and progressing special-process qualifications to unlock further opportunities in this high-value segment.”
Valiant supplies space-grade synchronization/timing components (GPS/GNSS/NavIC NTP servers, PTP grandmasters) to satellite operators and launch-vehicle companies such as Space Norway and Space One Japan.
“Supplied synchronization products to Space Norway AS, Space One Co. Ltd. (Japan), Turkmenergo (Turkmenistan), DTV Network, and the U.S. Armed Forces for satellite and defence synchronization requirements.”
Kavveri designs space-qualified antennas and microwave subsystems and has been engaged with the space industry since inception, with deep-space and high-gain solutions in its R&D pipeline.
“Kavveri's portfolio, from high-power multiband and pentaband antennas to space-qualified antennas, is already engaged there.”
ACS lists 'Space-Ground' as one of nine business domains, references satellite ground infrastructure work, and reports taking early steps into the space-defence domain.
“Our work in railway safety electronics, our early steps into the space-defence domain, and our AI capabilities position us to capture a meaningful share of this expanding market.”
RPP is constructing the NASPF and NDTF facilities at ISRO's SSLV launch complex in Tamil Nadu, supplying construction services to India's space launch programme.
“Construction of Nozzle assembly and segment preparation facility (NASPF) at SSLV Launch Complex , Thiruchendur and Sathankulam Taluk ,Tuticorin District for Rs. 22.52 crores.”
Definition used: Builds or operates satellites, launch vehicles, ground stations or space-grade components; supplies ISRO/commercial space programmes. Membership is extracted from each company’s newest annual report; every quote is validated against the report page before publishing, and core/growing tiers are confirmed by a second independent read (marked ). Companies whose reports our corpus hasn’t read yet simply aren’t listed — absence means unread, not “no exposure”.
MarketPing publishes facts, filings and measured history only — nothing on this page is investment advice, a recommendation or a rating.
