World's First Digital Sextant

-      The Korea Digital Sextant, developed by our company for the first time in the world, is a navigational device that facilitates the calculation of the position on a ship by mounting a Digital Unit on the existing sextant.

The Digital Unit has a built-in calculation function that automatically processes a series of procedures such as correction and calculation of Nautical Almanac, and LOP drawing, enabling quick and convenient position calculation.

Korea Digital Sextant is an emergency navigational device that guarantees the safe navigation of a ship by quickly calculating the position through celestial body sighting when the operation of GPS is restricted due to jamming or spoofing during sailing.

Development of Satellite navigation alternative technology for the navigation & combat system

• The present commercial ships or battle ships mainly depend on satellite navigation system for identifying its position.
• Reliability Problems of Satellite Navigation Systems  due to the present development of diverse radio disturbance technology.
• A desperate need for means to quickly identify the ship’s position without using satellite navigation and to adopt alternatives in the ship’s navigation / combat system under radio disturbance

Replace imports & create new industry through the connection of advanced overseas services 

• Localization of ship’s location identification system depending on the overseas satellite navigation system.

• Development of a Manual/Automatic Distribution System for Ship Positioning based on Celestial Navigation System

• Paradigm changes in shipbuilding Equipment and marine Industry with the Introduction of e-Navigation

Marine safety and environmental protection  by providing high value-added service

• IMO and  related international marine organizations are aware of the need for backup devices for satellite navigation system and actively discussing its alternatives

• Especially ,in the United States, Celestial navigation is recognized as a backup means of satellite navigation system.

• Standard interface application for ship distribution and commercialization
