Electronic Intelligence (ELINT) is intelligence gathered by detecting and analysing an adversary's electronic signals, mainly radar. India started with DRDO's single satellite EMISAT (PSLV-C45, 2019) [2]. It is now moving to networked constellations: TDB has given ₹64.05 crore of RDI support to Astrome's indigenous AI-ELINT constellation of 50 kg-class satellites in low Earth orbit (LEO) [1].

Role of AI in enhancing utility

  • Handling large data volumes: the payload covers a broad frequency range and collects huge amounts of signal data. AI-based ground software processes and interprets this complex data faster [1].
  • Identifying emitters: pattern recognition can classify a radar by type and platform, and can separate it from civilian signals.
  • Locating emitters: inter-satellite links make the satellites work as one network [1]. AI combines readings from several satellites to pinpoint where an emitter is.
  • Spotting changes: AI can flag a new deployment and point imaging satellites to it, so commanders can decide faster.
  • Limits: AI needs labelled training data and can raise false alarms. A human-in-the-loop must check its output.

Case for sovereign capability

  • Strategic autonomy: foreign partners can withhold or filter intelligence in a crisis. A national system keeps surveillance of areas of interest under Indian control [1].
  • Persistent coverage: many LEO satellites added in stages give steadily higher revisit over a target [1].
  • Data security: a national processing chain lowers the risk of leaks or tampered data.
  • Industrial base: the project takes technology from TRL-4 to TRL-9. Half of its ₹128.11 crore cost is co-funded through Optionally Convertible Debt [1], which builds private deep-tech capacity.

Concerns

  • Small satellites have less power and room for antennas than large ones, so the broad-band performance claim still has to be proven.
  • A private firm will build the system, but nobody has said who owns the data or how it is overseen. The government has stated that strategic capabilities stay under its control [3], and that principle needs to be written into this project.

AI turns ELINT constellations from signal collectors into tools that help commanders decide. Sovereign ownership ensures that this advantage cannot be denied in a crisis. The way forward:

  • the Ministry of Defence names a buyer for the output
  • AI output stays under human checks
  • a space law sets data-oversight rules

These steps would make the effort a lasting example of Atmanirbhar Bharat in strategic technology.
