Areas of Work

  • NPOL is developing a technology called seabed arrays that will be laid over the seabed surface for ocean surveillance which will provide measurements and inform the control centre about the happenings underneath through satellite. DRDO is planning a dedicated satellite for the coastal surveillance system.

All the future inductions planned by the Indian navy are to be fitted with NPOL designed sonars. The sonars under development are HUMSA NG (upgrade of the HUMSA sonar), the submarine sonars USHUS (for the Sindhugosh class) and PAYAL for the Arihant class.

Underwater acoustics is another area where NPOL is looking at. The Physical Oceanographic conditions which will decide the propagation of the sound waves inside water is studied with the help of DRDO's Research Vessel INS Sagardhwani and in-house developed Ocean models. Different Sonar Rnge Prediction models are also developed by NPOL in the recent years which are used by Indian Navy.

Famous quotes containing the words areas of, areas and/or work:

    The point is, that the function of the novel seems to be changing; it has become an outpost of journalism; we read novels for information about areas of life we don’t know—Nigeria, South Africa, the American army, a coal-mining village, coteries in Chelsea, etc. We read to find out what is going on. One novel in five hundred or a thousand has the quality a novel should have to make it a novel—the quality of philosophy.
    Doris Lessing (b. 1919)

    The discovery of the North Pole is one of those realities which could not be avoided. It is the wages which human perseverance pays itself when it thinks that something is taking too long. The world needed a discoverer of the North Pole, and in all areas of social activity, merit was less important here than opportunity.
    Karl Kraus (1874–1936)

    If there is a special Hell for writers it would be in the forced contemplation of their own works, with all the misconceptions, the omissions, the failures that any finished work of art implies.
    John Dos Passos (1896–1970)
