Detailed explanation-1: -The defence ministry has signed a contract with Bharat Electronics Limited (BEL) to procure a software-defined radio tactical (SDR-Tac) ship-borne system worth over Rs 1, 000 crore.
Detailed explanation-2: -The SDR-Tac is a four Channel Multi-mode, Multi Band, 19” Rack mountable, ship borne Software Defined Radio system. It is intended to serve ship-to-ship, ship-to-shore and ship-to-air voice and data communication for network centric operations.
Detailed explanation-3: -This SDR is used by the forces for transferring rates of voice, data, and video information. How does it help? “Troops on the ground that are carrying handheld portable SDR versions, will be able to integrate with higher echelons to achieve real C4I capability.
Detailed explanation-4: -The SDR-NC accommodates 10 waveforms for carrying voice and data traffic with proprietary encryption and frequency-hopping communications security. In terms of data rates, rates of 9.6 kiloBits-per-second (kBps) are achievable when using the HF radio, although this increases to 200kBps when using the VHF radio.
