Its vision is to make IRSA a global benchmark and promote export of IRSA-compliant SDR solutions to friendly nations. It defines interfaces, Application Programming Interfaces (APIs), execution environments, waveform portability, and SDR interoperability. It was developed under the Standardization of Indigenous SDR initiative by the Directorate of Standardization (DoS), Department of Defence Production (DDP), Ministry of Defence (MoD).
