The origin of the naval system technology in India can be traced to the establishment of the laboratory called Indian Naval Physical Laboratory (INPL) by Indian Navy in 1952 at Cochin in Kerala. It worked initially as a field laboratory mostly for fleet support activities. Later it was merged with DRDO in 1958 and started working on underwater systems. Subsequently, INPL was rechristened as NAVAL PHYSICAL OCEANOGRAPHIC LABORATORY (NPOL) which functioned from within the Naval Base in Kochi. In the year 1990, NPOL moved into the sylvan surroundings at Thrikkakkara, a suburb of Kochi.

The new campus, spread over 104 acres, has a main technical complex and two residential complexes - SAGAR and VARUNA. The technical complex houses the main building, Abhinavam building and several test facilities including an acoustic tank. Besides the campus in Thrikkakara, NPOL has an offsite setup of underwater acoustic research facility at Idukki lake, 100 km east of Kochi. NPOL also owns, since 1995, INS Sagardhwani, a 2000-ton Oceanographic research vessel used for oceanographic data collection.
