Overview

• IRSA 1.0 was formally released at a national workshop at DRDO Bhawan in New Delhi, bringing together the armed forces, DDP, DPSUs, industry, academia and research institutions.
• Defined as a comprehensive software specification for software-defined radios, IRSA sets standardized interfaces, APIs, execution environments and waveform portability mechanisms to support interoperability, certification and conformance.
• The initiative originated in 2021, a DRDO-led core team began work in 2022 with IDS and the Services, and the High-Level Advisory Committee approved Version 1.0 in 2025 as India’s first national SDR software architecture.
• Workshop sessions covered the specification’s technical overview, ecosystem roles and future directions, with discussions on collaboration opportunities, pilot projects, adoption pathways and conformance processes.
• The defence ministry framed the launch as a step toward self-reliance with a stated vision for IRSA to become a global benchmark and enable export of compliant solutions.
