Deck/Nautical Equipment/370227 ASTRO-NAVIGATION CALCULATOR, NC-2000

Digital navigation calculators for assessing the ship’s position by simple operation with built-in programs. Easy-to-understand dialogue system telling what input data is required, and what output data is displayed.  Major navigation functions are; -  Simple operation with built-in programs, -  Course and Distance computation. -  Dead Reckoning computation, -  Great Circle computation, -  ETA computation, -  Current computation. -  LOP computation. -  Meridian Passage computation. -  Convenient conversions for to HMS and to HHHH. -  Long term Nautical Almanac for the Sun, Moon, Venus, Mars, Jupiter, Saturn and 63 stars. The built-in Almanac is usable until 2100, and it is good with accuracy better than 0’.2.. -  Twilight time mode computes times of rise or set, civil twilight and azimuth for the Sun and rise or set, age and azimuth for the Moon, -  Prediction/identification mode computes azimuth and altitude for all celestial bodies and displays any usable bodies above the horizon, -  Can input Latitude and Longitude from optional GPS receiver.
