Key Details
TDB has signed a financing agreement with Bengaluru-based Astrome Technologies for a ₹128.11-crore space-technology project. The proposed constellation brings together:
50 kg-class microsatellites in low Earth orbit, carrying electronic intelligence (ELINT) equipment to detect and analyse signals;
AI-based ground software to process information collected by the satellites; and
inter-satellite communication links to help the spacecraft operate as a network.
TDB’s ₹64.05-crore support comes from the Research, Development and Innovation (RDI) Fund through optionally convertible debt—financing that can be converted into equity under its terms. The project aims to advance its core technologies from Technology Readiness Level (TRL) 4 to TRL 9 through development, integration and validation.
A Network Designed for More Frequent Observation
Electronic intelligence involves detecting and analysing signals emitted by electronic systems. Astrome proposes to collect such information from satellites and process it using AI-based software on the ground. As satellites are progressively added to the constellation, the network is intended to cover more areas and revisit places of interest more often.
Inter-satellite links are a key part of that design: they allow spacecraft to exchange information rather than function solely as separate observation points.
The Engineering Challenge Is Making Three Technologies Work Together
The project combines a signal-detection payload, ground-based analysis and satellite-to-satellite communications. Each has to be developed and tested, but system integration is the decisive step for a useful constellation.
The planned progression from TRL 4 to TRL 9 captures the scope of that work—from validated technology components towards a system proven in operation. TDB’s financing supports Astrome through this capital-intensive development phase.
What Is a Technology Readiness Level?
A Technology Readiness Level (TRL) indicates how far a technology has progressed from an initial idea towards proven use. The scale runs from TRL 1 to TRL 9. At TRL 4, key components have been validated in a laboratory. TRL 9 means the complete system has been proven in its intended operating environment.
For Astrome’s project, the goal is to move the satellite payload, AI-based analysis and communication links from component-level validation towards a working system in orbit.
Policy Relevance
The agreement directs public innovation finance towards a private Indian company developing technology for a national security application. It also illustrates what domestic capability requires in this field: satellite hardware, software to turn collected information into usable analysis, and communications that connect the spacecraft into a functioning network.
The project’s progress can be assessed through payload performance, successful integration, validated communication links and eventual deployment. These milestones will show how effectively RDI financing helps move complex Indian-made technology from development into use.
Relevant Question for Policy Stakeholders: What technical milestones and independent tests will demonstrate that Astrome’s proposed satellite system has progressed from validated components to reliable operation?
