PRECISE POSITIONING SYSTEM FOR HYDROGRAPHIC SURVEY BY THE MALACCA STRAIT COUNCIL OF JAPAN

Delivered to the Malacca Strait Council of Japan in November 1974, this precise positioning system was used for the hydrographic survey of the Lombok-Makasar Straits, executed from May through September 1975 by the Government of the Republic of Indonesia in cooperation with the Japanese Government. The waters surveyed are approx. 12 nautical miles in width and approx. 665 nautical miles in length. Inasmuch as efficiency of surveying operations can not be expected with conventional systems, this new system has been developed by IHI. The principal components of the system are NNSS (Navy Navigation Satellite System) and LORAN (Long Range Navigation)-C positioning system. With this new system, the data relating to the ship's position, as measured by the NNSS and LORAN-C, are immediately computed by two computers, and thus ship's positions are obtained as output from typewriters. Besides hydrographic surveys, this system can be used for surveys on continental shelves for the development of oil and fishery resources.
