Why DRDO's successful field trials of Software Defined Radio and CTCS are important

Defence Electronics Application Laboratory (DEAL), a unit of Defence Research & Development Organisation, carried out successful field trials of a compact Software Defined Radio (SDR) and Compact Transhorizon Communication System (CTCS)—both having implications in mission-critical communication technology for national security.

 

According to DRDO, "SDR is a secure indigenous system with legacy communication support and secure digital voice/data communication for Naval application with 3 channel (2V/UHF band and 1 HF band), 4-channel (2V/UHF band and 2L-band)for Tactical Communication and single channel operation in V/UHF (Manpack role) and UHF band (Handheld role)."

 

CTCS is a "large hop terrestrial backhaul communication system" for ensuring high data rate connectivity to user stations and remote locations. This system can be used in remote locations where civil communication grid is not present.

"Both the systems demonstrated robust and reliable performance meeting the user defined operational benchmarks. The milestone reinforces the commitment of DRDO in developing indigenous and mission critical communication solution for national security," the DRDO said in a social media post.

 

The trials were conducted in varied terrain and operational environments, aiming to rigorously validate the performance of both the systems in real-world conditions, including "verification of key parameters as per QR & Tds."

 

SDR can enable encrypted, real-time voice and data transfer for Army, Navy, and Air Force units,  streamlining joint operations, while CTCS can secure and robust connectivity for defence forces in challenging environments.
