The SDR-Tac is a four channel multi-mode, multi-band, 19-inch rack mountable, ship-borne software defined radio system, it said.

The worth of this software is over 1,000 crore. The agreement signed during the ‘Bandhan’ ceremony at Aero India 2021 at Air Force Station Yehalanka in Bengaluru.

The SDR-Tac, jointly developed by Navy, BEL, Defence Research and Development Organisation (DRDO) and DEAL, will bring strategic depth to the Armed Forces.

What is SDR-Tac?

SDR-Tac, a four Channel Multi-mode, Multi-Band, 19’’ Rack mountable, shipborne Software Defined Radio system serves ship to ship, ship to shore and ship to air voice and data communication for network-centric operations.

It supports the operation of all the four channels covering V/UHF and L Band, parallely. This SDR system has different types of waveforms for narrowband and wideband applications.

The MANET waveforms are available in UHF and L-Band to support adhoc networking feature for net-centric operations. User evaluation trials covering exhaustive harbour phase and sea phase trials were completed successfully during May to June 2018 at Visakhapatnam for all waveforms including V/UHF and L-Band MANET waveforms under different network configurations.
