NO GPS! NO Sensor!

The DIGITAL SEXTANT which is the world's first developed navigation equipment by LEEYOUNG SND
that can be used to calculate and identify the ship’s position by installing electronic device on the conventional Sextant.
The electronic device is the new technology developed to enable a navigation officer
to calculate and identify the ship’s position rapidly and conveniently through the embedded
computing function that automatically processes all necessary procedures to calculate and identify ship’s position,
such as the correction and calculation of astronomical calendar, drawing ship’s position lines, etc.
The DIGITAL SEXTANT can be used very effectively as the auxiliary equipment of the existing GPS navigation system
in an emergency that guarantees the safe navigation by quickly calculating and identifying the ship’s position,
observing 57 celestial bodies, such as the sun, moon, polar star, etc when the failure or malfunction of the
existing GPS navigation system occurs due to Jamming or other radio disturbances during ship’s voyage.

Major Features
  • Ship’s current position can be identified by observing the sun, moon, polar star and solar system planets including Selected 57 Navigational Stars
  • The electronic device of DIGITAL SEXTANT has the computing function to process the astronomical calendar information
  • The electronic device reflects the geographical position calculation algorithm
  • Exact time keeping available by an embedded Real-Time Clock
  • Convenient charging available via Micro-USB port
  • Continuous operation for above 7 hours is possible through a single full charge(The operation will be available for approx. above one month when selecting two times Sighting mode per day)
  • Even a beginner of astronomical navigation can conveniently calculate the ship’s position
  • Provide a detachable sunscreen for LCD display
  • Provide a high performance shielding case for electromagnetic pulse attack (EMP attack) (as an option)
  • IMO & Non-IMO Ships
  • Naval Ships, Coast Guard Ships, Government Ships
  • School Training Ships, Lifeboats of Ships
  • Leisure Yachts and Boats, etc
