A Defence Research and Development Organisation (DRDO) unit has successfully completed field trials of a compact software defined radio (SDR) and a key communication system, furthering efforts to develop indigenous, mission-critical communication technology for national security.
The trials were conducted by DRDO’s Defence Electronics Application Laboratory (DEAL), Dehradun, in Joshimath, Uttarakhand. The exercise was carried out in close collaboration with the Ministry of Home Affairs, central armed police forces (CAPFs), and other concerned agencies.
The SDR is a secure, indigenous system offering support for legacy communications as well as encrypted digital voice and data transmissions. It supports naval applications with a 3-channel setup (two V/UHF band and one HF band), a 4-channel configuration (two V/UHF and two L-band) for tactical communications, and allows single-channel operations in V/UHF (for manpack use) and UHF (for handheld use). In addition, the compact terrestrial communication system (CTCS) developed by DEAL is a long-hop terrestrial backhaul communication platform that provides high-data-rate connectivity to remote and user locations. It is especially useful in areas without access to civilian communication infrastructure.
