Advanced VLF Demodulator

Product category :Naval Systems

Very Low Frequency (VLF) is the means of long-range reliable communication from Indian mainland to distributed ships and submerged submarines. Indian Navy established a VLF Transmitting station at INS Kattabomman for this purpose. Limited bandwidth of the large transmit antenna is a major challenge in achieving enhanced information transfer rate over this link. Advanced VLF Demodulator system is a solution to this challenge which is able to achieve reliable text data communication up to 400 bps in available 200 Hz bandwidth by use of modern communication signal processing techniques. Adv VLF Demodulator is interfaced at IF of 36KHz.
