# Defence Space Agency

The Defence Space Agency (DSA) is an integrated tri-services agency of the Indian Armed Forces headquartered in Bengaluru, Karnataka, India. The agency is tasked with operating the space-warfare and Satellite Intelligence assets of India. The DSA draws personnel from all three branches of the Armed Forces.
The agency is expected to be converted into a full sized tri-service military command in the future.

## History
### Origins

The Naresh Chandra Task Force was set up in July 2011 by National Security Advisor Shivshankar Menon to review the recommendations of the Kargil Review Committee, assess the implementation progress and further suggest new reforms related to national security. The task force was led by Naresh Chandra, retired Indian Administrative Service officer, and comprised 13 other members, including Gopalaswami Parthasarathy, Air Chief Marshal Srinivasapuram Krishnaswamy (Retd), Admiral Arun Prakash (Retd), Lt Gen V. R. Raghavan (Retd), Anil Kakodkar, K C Verma and V K Duggal. The committee conducted the first holistic review of national security since the Kargil Review Committee and submitted its classified report to Prime Minister Manmohan Singh on 23 May 2012. Among its recommendations, the Task Force recommended the creation of a cyber command, an aerospace command and a special operations command. All three units were proposed to be tri-service commands. The DSA is a downsized implementation of this proposal.
The creation of the Defence Space Agency (DSA), the Defence Cyber Agency (DCA), and the Armed Forces Special Operations Division (AFSOD) was approved by Prime Minister Narendra Modi during the Combined Commanders' Conference at Jodhpur Air Force Station on 28 September 2018. The Defence Imagery Processing and Analysis Centre in Delhi and the Defence Satellite Control Centre in Bhopal were subsumed by the DSA.

### Anti-satellite programme of India

Months before the operationalisation of the Defence Space Agency, India conducted an Anti-satellite weapon (ASAT) test in March 2019. The test was aimed at demonstrating India's anti-satellite capability.
The Indian ASAT programme can be traced back to its BMD program, which began in 1999 in response to threats posed by the Ballistic missiles of Pakistan and China. In 2006 and 2007, India tested its first exo atmospheric interceptor and has developed many interceptors since then. On 18 March 2008, DRDO Chief V. K. Saraswat had hinted that India possessed technology required for an ASAT missile, reiterating it in February 2010. India is known to have been developing an exo-atmospheric kill vehicle that can be integrated with the missile to engage satellites. In April 2012, Saraswat again said that India possessed the critical technologies for an ASAT weapon from radars and interceptors developed for Indian Ballistic Missile Defence Programme. India had begun work on its ASAT soon after the 2007 Chinese anti-satellite missile test.
As of April 2019, India was working on directed energy ASAT weapons, co-orbital ASAT weapons, lasers and electromagnetic pulse (EMP) based ASAT weapons. The ability to protect space assets from hostile electronic and physical attacks was also being developed by India.

### Expansion

It was reported in late 2023 that the Indian Air Force (IAF) has proposed to rename itself as the Indian Air and Space Force (IASF) with an enhanced focus on space-based capabilities India also plans to have over 100 small and large military satellites within 7 to 8 years with the DSA to expand into a full-fledged Space Command.
After the approval of 52 surveillance and communication satellites for the Indian Armed Forces, the Department of Military Affairs gave a detailed presentation to the senior members of the Ministry of Defence and key stakeholders from ISRO and DRDO in December 2024. According to a report, plans are being devised to strengthen the Defence Space Agency and other related organisations by increasing the agency's manpower, ground-based infrastructure, space-based assets as well as ensuring their protection from threats. These steps are being taken to enhance India's space-centric warfare capabilities.

### Exercise
#### IndSpaceEx

India conducted its first simulated space warfare exercise on 25th and 26 July 2019, called IndSpaceEx. The exercise was conducted under the supervision of Integrated Defence Staff. The exercise was aimed at obtaining an assessment of threats and the creation of a joint space warfare doctrine.

#### Antariksh Abhyan

The first edition of the exercise was conducted from 11 to 13 November 2024 by Headquarters Integrated Defence Staff. The exercise will simulate various scenarios of war-game the growing threats from and to Space Based Assets and Services.

## Space Based Surveillance

The Space Based Surveillance is a series of projects taken up by the Government of India to launch a constellation of satellites for earth observation roles. Additionally, the Indian Armed Forces also operates communications satellites of the GSAT-7 series of which GSAT-7 and GSAT-7A are active while GSAT-7B, GSAT-7C and GSAT-7R are planned for launch.
The Phase-I project was approved by the PM Atal Bihari Vajpeyee in 2001. In this phase, 4 satellites — Cartosat-2A, Cartosat-2B, EROS B and RISAT-2 — were launched.
The Phase-II project was approved by the government on 2013 as a part of which 6 satellites — Cartosat-2C, Cartosat-2D, Cartosat-3A, Cartosat-3B, Microsat-TD, RISAT-2A — were approved for development and launch.

### SBS Phase-III

On 12 October 2024, India's Cabinet Committee on Security approved a proposal for the development, construction and launch of a constellation of 52 spy satellites as a part of the Space Based Surveillance Phase-III project intended to enhance the country's surveillance capabilities from space in both land and sea domains. The project, worth ₹26,968 crore (US$3.1 billion), will be supervised by National Security Council Secretariat along with the Defence Space Agency under the Integrated Defence Staff. The constellation will also enhance the SATCOM capabilities of long range UAVs of the Armed Forces like the MQ-9B Predator drones that are on order. The SBS system will provide round-the-clock monitoring, irrespective of weather, time of day or atmospheric conditions and may have secondary civilian applications as well. All the satellites is to be launched within 5 years at Geosynchronous Equatorial Orbit (GEO) and Low Earth Orbit (LEO). The satellites will be equipped with artificial intelligence for inter-satellite communications.
As part of the project, 21 satellites will be co-developed by ISRO and France (under the LoI agreement for “defence space cooperation”) while the rest of 31 satellites are to be developed by three private sector companies. The role of these satellites would be surveillance, reconnaissance, communication and other strategic purposes. The CCS has also, reportedly, approved two agencies to develop multiple types of defensive and offensive capabilities from space. Under the same project, few experiments would be conducted for an integrated LEO and MEO satellite-based communication system which is a requirement for the Air Force and the Navy. The first batch of satellites will be launched in 2027-28.

### List of Indian military satellites

As of 2024, India operates 9 military satellites. Of these, three strategic satellites including two communication satellites (GSAT-7 and GSAT-7A) are for dedicated military use, while the rest are dual-purpose satellites with military and civilian applications.

#### Decommissioned

* Technology Experiment Satellite or (TES) is an experimental satellite to demonstrate and validate, in orbit, technologies that could be used in the future satellites of Indian Space Research Organisation (ISRO). The Technology Experiment Satellite (TES) has a panchromatic camera capable of producing images of 1 meter resolution for remote sensing. The launch of TES made India the second country in the world after the United States that can commercially offer images with one meter resolution. It is used for remote sensing of civilian areas, mapping industry and geographical information services.
* RISAT-2, or Radar Imaging Satellite 2 has a primary sensor, the synthetic aperture radar from Israel Aerospace Industries (IAI). RISAT-2 is India's first satellite with a synthetic aperture radar. It has a day-night, all-weather monitoring capability and has a resolution of one metre. Potential applications include tracking hostile ships at sea. Though the Indian Space Research Organisation sought to underplay the satellite's defence capabilities in its website and in its announcements, a majority of the media preferred to classify it as a spy satellite. ISRO claims that the satellite will enhance ISRO's capability for earth observation, especially during floods, cyclones, landslides and in disaster management in a more effective way.
* CARTOSAT-2 carries a state-of-the-art panchromatic (PAN) camera that take black and white pictures of the Earth in the visible region of the electromagnetic spectrum. The swath covered by these high resolution PAN cameras is 9.6 km and their spatial resolution is 80 centimetres. The satellite can be steered up to 45 degrees along as well as across the track. CARTOSAT-2 is an advanced remote sensing satellite capable of providing scene-specific spot imagery. The data from the satellite will be used for detailed mapping and other cartographic applications at cadastral level, urban and rural infrastructure development and management, as well as applications in Land Information System (LIS) and Geographical Information System (GIS). Cartosat was decommissioned and the perigee lowered by controlled burns between March and Sep 2020 as debris mitigation activities. This will result in the orbit naturally decaying and re-entry within 10 years.
* GSAT-6A is a dedicated satellite for army as a replacement for GSAT-6 which lost communication after its launch.
* Microsat-R, a dedicated military satellite for the Indian Armed Forces, was launched on 24 January 2019. The 760 kg imaging satellite was launched using PSLV C-44 rocket.
