• The Defence Research and Development Organisation (DRDO), in collaboration with the Integrated Defence Staff and the Tri-Services, recently released Indian Radio Software Architecture (IRSA) standard 1.0.
• IRSA represents India’s first national specification for standardized software architecture for Software Defined Radios (SDR).

HIGHLIGHTS

About IRSA

• Provides a standardized framework defining how different radio systems communicate securely and efficiently.
• Aims to position India as a global benchmark in SDR technology.
• Supports India’s vision of exporting IRSA-compliant solutions to friendly nations.

Key Features of IRSA

• Comprehensive software specification for SDR systems.
• Defines standardized interfaces, APIs, execution environments, and waveform portability mechanisms.
• Supports SDR interoperability, certification, and conformance.
• Places India alongside global SDR frameworks:
  • US Software Communications Architecture (SCA)
  • Europe’s ESSOR
  • NATO’s STANAG SDR standards
• Prepared under the Standardization of Indigenous SDR initiative of the Directorate of Standardization (DoS) under the Department of Defence Production (DDP), Ministry of Defence (MoD).

What is Software Defined Radio (SDR)?

• SDR is a radio communication system that uses reconfigurable software-based components to process and convert digital signals.
• Offers high flexibility and versatility, unlike traditional radios.
• Enables seamless connection in an ever-increasing wireless ecosystem.
