India will soon have its own satellites to monitor spy satellites. How the technology works
The project being undertaken by the Defence Ministry, which is in the process of being finalised, will have 'satellite mapping' capabilities and will be fully made in India, senior officials from the Indian Space Research Organisation (ISRO) told ThePrint.
New Delhi: Spy satellites to monitor other spy satellites. India will soon have its own constellation of satellites to keep an eye out for other satellites that might be surveilling India.
This network of satellites will enhance India's space domain awareness and will also help monitor orbital threats in real-time. The project is being overseen under NETRA, a Network for Tracking Space Objects and Analysis, which detects space debris and other hazardous space objects.
The official said that while ISRO will partner with the MoD in overseeing the overall design and monitoring of these satellites, a private Bengaluru-based space start-up, Digantara, has been contracted to deploy these satellites within the next year.
How does satellite mapping work?
The capabilities of monitoring foreign satellites is being acquired by countries including the US, Russia and China.
These satellites have propulsion and guidance systems that utilise factors such as orbital inclinations and altitudes to get information and photographs from a potential target satellite.
Some of these satellites are also capable of intercepting inter-satellite communications and links to ground stations.
Varying versions of such technology are either already deployed or are currently being tested. In 2020, the US Space Command—an agency responsible for tracking all objects in orbit—flagged that the Russian satellite Kosmos 2543 had released an unknown object into space. This was believed to be a test of a new technology that could be used to destroy objects already in orbit.
The Russian satellite released this tech in close proximity to another Russian satellite.
'Space is increasingly becoming a weapon for countries. Battles will no longer be limited to just the ground, but will also be fought in space. And countries need to be ready for it,' the ISRO official said.
Focus on active orbital security
India is already working on increasing its defence capabilities in space.
Its next 'spy satellite programme', space-based surveillance-3 or SBS-3, will launch a constellation of 52 surveillance satellites in the coming two years. Three private space startups, Ananth Technologies, Centum Electronics and Alpha Design Technologies, have joined hands with the government to give shape to this project.
The Rs 27,000 crore project is set to significantly improve India's national security capabilities.

Speaking to DH, Regional Transport Officer H S Bhagavan Das said that people are keen to buy electric vehicles as they are cost-effective and generally produce less pollution than gasoline or diesel cars, particularly in terms of tailpipe EVs themselves have zero tailpipe emissions as they don't release pollutants directly into the air. Besides, EV vehicle owners need not spend much on maintenance in terms of changing engine oil as in the case of traditional considering the number of electric vehicles, the charging points are very minimal in the city. Except for the one run by Bescom at Ambedkar Circle, the charging points are limited in the city. Speaking to DH, Dhananjay, who owns EV car said 'I charge my car near my household. When I need it fast, I visit the recharge station and it would take about one hour and the fare is around Rs 300.'It had been decided to set up charging points at a total of 21 places in Davangere district under public-private-partnership model. A proposal has already been submitted to the government to set up the stations at government-owned, currently vacant 30X40-area sites such as the deputy commissioner's office, taluk office, zilla panchayat, mini Vidhana Soudha, general hospital and bus terminals. These stations with a capacity of 90 KW will operate 24 hours a day. To keep it functional round-the-clock, it is planned to ensure continuous electricity supply. 'As per the government's instructions, 21 places have been identified in the district to conduct a survey and to set up charging points. The construction work of these will be taken up after the government's further orders,' Bescom Executive Engineer A K Thippeswamy told DH.'Bescom is operating a charging station on an experimental basis near Ambedkar Circle. The users have to download EV app on their mobile phone and scan the code for charging the vehicle. They have to pay fare via digital payment. It is not being operated manually, however,' he added. He further said that it was decided to set up charging points on the premises of 12 Indian Oil Corporation Limited fuel stations in the city. Of them, only five have paid the fee to Bescom to set up the infrastructure.
