About Lab

Naval Physical & Oceanographic Laboratory (NPOL) is an ISO 9001:2008 certified premier R&D establishment of the Defence Research and Development Organization (DRDO), Ministry of Defence, Govt. of India. It was established in 1952as a Naval testing laboratory of Indian Naval Physical Laboratory (INPL) in the Naval Base, Kochi. After becoming a part of DRDO, it was shifted to the present campus at Thrikkakara in 1990. The laboratory has the main campus at Thrikkakara also has a test & evaluation facility at Kulamvu, Idukki. The Lab also own a research vessel called the INS Sagardhwani. It is the only unit of DRDO in the state of Kerala.

npolThe laboratory is 'System Laboratory' of DRDO engaged in the development of SONAR (Sound Navigation And Ranging) and allied technologies. The thrust areas of R&D of the laboratory are Signal processing, Electronics, Engineering systems, Transducers, Materials and Oceanography. The laboratory has developed hull mounted sonars for ships and submarines, towed array sonars and airborne sonars. NPOL's work in this area has helped the nation achieve self-reliance in this vital area.

 

 

npolThe origin of the Naval Physical & Oceanographic Laboratory (NPOL) dates back to 1949, when the Government of India invited Dr. J. E. Keyston of the Royal Naval Scientific Service, UK to advise on the establishment of a Scientific Organization to assist the Indian Navy. Consequently, the Indian Naval Physical Laboratory (INPL) was set up in 1952 as an in-house laboratory of Indian Navy for providing scientific support. The laboratory was located in a barrack at the Naval Base, Kochi. When the Defence Research and Development Organization (DRDO) was formed in 1958, INPL was absorbed into the new organization. Later in 1969, when oceanography assumed a principal role in the research interests of the Laboratory, INPL was rechristened Naval Physical & Oceanographic Laboratory (NPOL). Thus, it enjoys distinction of having existed prior to the DRDO itself. NPOL has grown from a fleet support laboratory of the Indian Navy to a sonar systems developer during the last six decades. Today, NPOL stands tall with great pride for its outstanding achievements and contributions in the areas of Sonar research and development for Indian Navy.


npolNPOL started as a field unit of Indian Navy for the servicing of electro-acoustic transducers. Then slowly, it graduated into ocean data collection and its interpretation, followed by servicing of electronic equipment. Since 1980, the laboratory has grown into a system laboratory integrating various disciplines like transducers, oceanography, electronics, engineering, material science, etc. The vintage systems of 1980 evolved with wire wrapped models followed by Development and Engineering the system for onboard trials by the production agency. Then the laboratory graduated to a model where orders were directly placed with the production agency based on NPOL's design and prototype. With the advent of industrial infrastructure in the 2000's NPOL implemented another model system development was done concurrently with industries also.



npolNPOL is situated in a suburb of Kochi called Thrikkakara approximately 16 km from Ernakulam Junction railway station and 24 km from Cochin International Airport. Thrikkakara is well connected by road from railway station and airport and is one km from district headquarters
