The Union Ministry of Defence on 29 November 2017 approved procurement of 260 Software Defined Radios (SDR) for the Indian Navy.
The decision was taken at a meeting of the Defence Acquisition Council (DAC) chaired by Defence Minister Nirmala Sitharaman. The DAC is defence ministry’s highest decision making body on procurement.
• The naval communication sets have been procured to scale up surveillance on the high seas.
• They will be the first batch of indigenously designed and developed ‘software defined’ radio sets.
• They will be replacing the existing old systems on-board warships.
• The technology will improve information sharing through secure voice communications and data transfer capabilities on board the naval ships.
• The cost of the 260 communication gadgets is expected to be around Rs 490 crore.
What is SDR technology?
It is a radio communication system where components that have been traditionally implemented in hardware are instead implemented by means of software on a personal computer or embedded system.
The development of the communication sets was carried out by Defence Electronics & Applications Laboratory (DEAL) of Defence Research and Development Organisation (DRDO).
Bharat Electronics Limited (BEL) will be the production agency.
