DRDO Unveils IRSA 1.0

On 6th October 2025, the Defence Research and Development Organisation (DRDO), in collaboration with the Integrated Defence Staff (IDS) and the Tri-Services, launched the Indian Radio Software Architecture (IRSA) Standard 1.0 in New Delhi, marking a landmark step toward indigenous and interoperable defence communication systems.

The Indian Radio Software Architecture (IRSA) 1.0 is a unified software framework for Software Defined Radios (SDRs), defining standardized interfaces, APIs, execution environments, and waveform portability mechanisms across India’s armed forces.
The standard aims to ensure seamless waveform portability, interoperability, certification, and conformance across SDR platforms used by the Army, Navy, and Air Force, thereby enhancing communication efficiency and operational coordination.
