The facility which is located in Mahendragiri was formerly called LPSC-Mahendragiri and was declared a separate centre. It handles testing and assembly of liquid propulsion control packages, liquid engines, and stages for launch vehicles and satellites.[1]

U R Rao satellite centre

The venue of eight successful spacecraft projects located in Bangalore, is also one of the main satellite technology bases of ISRO. The facility serves as a venue for implementing indigenous spacecraft in India.[1] The satellites Aryabhata, Bhaskara, APPLE, and IRS-1A were built at this site, and the IRS and INSAT satellite series are presently under development here. This centre was formerly known as ISRO Satellite Centre.[2]

Laboratory for electro-optics systems

This is the Unit of ISRO which responsible for the development of altitude sensors for all satellites and is located in Bangalore. The high precision optics for all cameras and payloads in all ISRO satellites are developed at this laboratory, located at Peenya Industrial Estate, Bengaluru.

Satish dhawan space centre

With multiple sub-sites the Sriharikota island facility acts as a launching site for India's satellites.[1] The Sriharikota facility is also the main launch base for India's sounding rockets.[2] The centre is also home to India's largest Solid Propellant Space Booster Plant (SPROB) and houses the Static Test and Evaluation Complex (STEX).[2] The Second Vehicle Assembly Building (SVAB) at Sriharikota is being realised as an additional integration facility, with suitable interfacing to a second launch pad.[6][7]

Thumba equatorial rocket launching station

TERLS which is located in Thiruvananthapuram, is used to launch sounding rockets.[8]

Indian deep space network

IDSN network which is located in Bangalore, receives, processes, archives and distributes the spacecraft health data and payload data in real-time. It can track and monitor satellites up to very large distances, even beyond the Moon.[9]

National remote sensing centre

The NRSC which is headquartered in Hyderabad, applies remote sensing to manage natural resources and study aerial surveying.[1] With centres at Balanagar and Shadnagar it also has training facilities at Dehradun acting as the Indian Institute of Remote Sensing.[1]

ISRO telemetry, tracking and command network

This facility's headquarters is located in Bangalore and it also has a number of ground stations throughout India and the world.[4] Software development, Ground Operations, Tracking Telemetry and Command (TTC), and support is provided by this institution.[1] ISTRAC has Tracking stations throughout the country and all over the world in Port Louis (Mauritius), Bearslake (Russia), Biak (Indonesia) and Brunei.[10]

Master control facility

MCF which is located in both Hassan and Bhopal, is mainly used for geostationary satellite orbit raising, payload testing, and in-orbit operations are performed at this facility.[11] The MCF has Earth stations and the Satellite Control Centre (SCC) for controlling satellites.[11] A second MCF-like facility named 'MCF-B' is being constructed at Bhopal.[11]

Space situational awareness control centre

This facility which is located in Peenya and Bangalore, has a network of telescopes and radars are being set up under the Directorate of Space Situational Awareness and Management to monitor space debris and to safeguard space-based assets. The new facility will end ISRO's dependence on Norad. The sophisticated multi-object tracking radar installed in Nellore, a radar in Northeast India and telescopes in Thiruvananthapuram, Mount Abu and North India will be part of this network.[12][13]

Directorate of space situational awareness and management

To reduce dependency on North America Aerospace Defense Command (NORAD) for space situational awareness and protect the civilian and military assets, ISRO is setting up telescopes and radars in four locations to cover each direction. Leh, Mount Abu and Ponmudi were selected to station the telescopes and radars that will cover North, West and South of Indian territory. The last one will be in Northeast India to cover the entire eastern region. Satish Dhawan Space Centre at Sriharikota already supports Multi-Object Tracking Radar (MOTR).[14] All the telescopes and radars will come under Directorate of Space Situational Awareness and Management (DSSAM) in Bengaluru. It will collect tracking data on inactive satellites and will also perform research on active debris removal, space debris modelling and mitigation.[15]

For early warning, ISRO began a ₹400 crore (4 billion; US$53 million) project called Network for Space Object Tracking and Analysis (NETRA). It will help the country track atmospheric entry, intercontinental ballistic missile (ICBM), anti-satellite weapon and other space-based attacks. All the radars and telescopes will be connected through NETRA. The system will support remote and scheduled operations. NETRA will follow the Inter-Agency Space Debris Coordination Committee (IASDCC) and United Nations Office for Outer Space Affairs (UNOSA) guidelines. The objective of NETRA is to track objects at a distance of 36,000 kilometres (22,000 mi) in GTO.[16][17]

India signed a memorandum of understanding on the Space Situational Awareness Data Sharing Pact with the US in April 2022.[18][19] It will enable Department of Space to collaborate with the Combined Space Operation Center (CSpOC) to protect the space-based assets of both nations from natural and human-made threats.[20] On 11 July 2022, ISRO System for Safe and Sustainable Space Operations Management (IS4OM) at Space Situational Awareness Control Centre, in Peenya was inaugurated by Jitender Singh. It will help provide information on on-orbit collision, fragmentation, atmospheric re-entry risk, space-based strategic information, hazardous asteroids, and space weather forecast. IS4OM will safeguard all the operational space assets, identify and monitor other operational spacecraft with close approaches which have overpasses over Indian subcontinent and those which conduct intentional manoeuvres with suspicious motives or seek re-entry within South Asia.[21]

ISRO system for safe and sustainable space operations management

On 7 March 2023, IS4OM conducted successful controlled re-entry of decommissioned satellite Megha-Tropiques after firing four on-board 11 Newton thrusters for 20 minutes each. A series of 20 manoeuvres were performed since August 2022 by spending 120 kg fuel. The final telemetry data confirmed disintegtration over Pacific Ocean. It was part of a compliance effort following international guidelines on space debris mitigation.[22]

Advance space research group

Like NASA funded Jet Propulsion Laboratory (JPL) managed by California Institute of Technology (Caltech), ISRO with Indian Institute of Space Science and Technology (IIST) implemented a joint working framework in 2021 in which an Empowered Overseeing Committee (EOC) under Capacity Building Programme Office (CBPO) of ISRO located in Bengaluru will approve all short, medium and long term space research projects of common interest. In return, an Advance Space Research Group (ASRG) formed at IIST under the guidance of EOC will have full access to ISRO facilities. The primary aim is to transform IIST into a premier space research and engineering institute by 2028–2030 that can lead future space exploration missions of ISRO.[29][30]
