What is Software-Defined Radio Tactical (SDR-Tac)?

What is a Software Defined Radio (SDR)?

• SDR is a radio communication system that employs reconfigurable software-based components for the processing and conversion of digital signals.
• Unlike traditional radio communication systems, these radio devices are highly flexible and versatile.
• This is an emerging technology used to connect ever-increasing wireless world.

About Software-Defined Radio Tactical (SDR-Tac):

• Equipped with several multimedia capabilities, the indigenous SDR-Tac provides real-time voice, data and video information.
• It is built indigenously by the Navy’s Weapons and Electronics Systems Engineering Establishment (WESEE).
• What does SDR-Tac do?
  • SDR-Tac is a four-channel multi-mode, multi-band, 19-inch rack-mountable, ship-borne software-defined radio system.
  • It is intended to serve ship-to-ship, ship-to-shore, and ship-to-air voice-data communication for network-centric operations.
  • It supports the simultaneous operation of all four channels covering V/UHF- and L-Band.
  • This SDR system houses multiple types of waveforms for narrow-band and wide-band applications.
  • Each ship will act as a relay wherein the data can jump from one ship to another. 
  • To transfer voice, data or video, the link device picks up the best-suited available network.  It ensures that data reaches its destination.
