The Indian Army has taken a major step towards self-reliance in defence communication by signing a contract to procure its first indigenously designed and manufactured Software Defined Radios (SDRs).
Developed by the Defence Research and Development Organisation (DRDO) and produced by Bharat Electronics Limited (BEL), these advanced radios come equipped with high data rates and Mobile Ad hoc Network (MANET) capabilities, enabling secure, real-time communication across diverse and dynamic battlefield environments.
This procurement of software defined radios aligns with the recently launched Indian Radio Software Architecture (IRSA) version 1.0, a national software standard for SDRs developed collaboratively by DRDO, Integrated Defence Staff, and the Tri-Services. IRSA ensures interoperability, certification, and waveform portability, providing a unified architecture for India’s military communication systems.
This landmark contract marks a significant boost for India’s goal of Atmanirbhar Bharat in defence electronics, ensuring modern, network-centric warfare capabilities while reducing dependence on foreign equipment. The indigenously developed SDRs are expected to play a pivotal role in enhancing secure communications and coordination among Indian Army units across different terrains and operational scenarios.
This initiative also paves the way for an expanding technology ecosystem involving defence PSUs, industry, and academia to support future upgrades and potential exports of IRSA-compliant communication systems, furthering India’s strategic autonomy in military technology.
Key Comments
An official from Bharat Electronics Limited commented, “We are proud to manufacture cutting-edge SDRs that not only enhance the Indian Army’s operational readiness but also strengthen India’s position as a leader in indigenous defence technology. The collaboration with DRDO on IRSA standard underscores our commitment to advanced, interoperable communication solutions.”
