Indian Radio Software Architecture 1.0 (IRSA) launched by DRDO enhances military radio interoperability across Army, Navy, and Air Force, promoting indigenous defense technology.
DRDO Launches IRSA 1.0 for Military Radio Interoperability
Introduction: DRDO Unveils Indian Radio Software Architecture (IRSA) 1.0
On October 6, 2025, the Defence Research and Development Organisation (DRDO), in collaboration with the Integrated Defence Staff (IDS) and the Tri-Services, officially launched the Indian Radio Software Architecture (IRSA) standard 1.0. This initiative aims to enhance interoperability among military communication systems across the Army, Navy, and Air Force. The unveiling took place during a national workshop at DRDO Bhawan in New Delhi.
What is IRSA 1.0?
IRSA 1.0 is a comprehensive software specification designed for Software Defined Radios (SDRs). It establishes standardized interfaces, application programming interfaces (APIs), execution environments, and mechanisms for waveform portability. The architecture ensures that SDR systems are interoperable, certified, and conform to national standards. This standardization is crucial for seamless communication across different military platforms.
Development Journey and Stakeholder Collaboration
The IRSA initiative commenced in 2021, recognizing the critical role of SDRs in modern military communication. A core technical team led by DRDO initiated work in 2022, engaging with the Integrated Defence Staff (IDS) and the three services to capture operational and user requirements. After extensive reviews and consultations with stakeholders, IRSA version 1.0 was approved and became India’s first national specification defining a standardized software architecture for SDRs.
Strategic Significance of IRSA
The launch of IRSA represents a defining step in India’s journey toward self-reliance in defence communication technologies. It embodies the vision of building indigenous, interoperable, and future-ready SDR solutions—designed in India, for India, and ready for the world. The specification is designed to evolve with operational requirements and lays the foundation for integrating future technologies.
Workshop Highlights and Future Directions
The national workshop served as a platform to share technical details and discuss pilot projects. It encouraged partnerships among the tri-services, industry, and academia. The event emphasized a collaborative approach to building a robust indigenous defence communication ecosystem. Looking ahead, IRSA is intended to be a living standard that adapts to new technologies and operational challenges, positioning India as a global leader in SDR architecture.
