370227 – ASTRO-NAVIGATION CALCULATOR, NC-2000

IMPA 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 ; 1. Long term Nautical Almanac for the Sun, Moon, Venus, Mars, Jupiter, Saturn and 63 stars. The built-in Almanac is usable for the years 1583 to 2100, however it is good with accuracy better than 0’.2 through the year 1900 to 2100. 2. Twilight time mode computes times of rise, set and civil twilight and azimuth for the Sun and rise, set, age and azimuth for the Moon 3. rediction/identification mode computes azimuth and altitude for the all celestial bodies and displays any usable bodies above the horizon. The celestial body can be arranged in order of azimuth or altitude. 4. Most accurate course and distance/dead reckoning computation by Mercator Sailing on the IAU 1976 Spheroid. 5. Quick course planning by latitude examination on the Great Circle track and Composite Sailing track. 6. Tide at standard port. 7. Estimated time of arrival computation. 8. Convenient conversions for to HMS (Hour, Minute, Second) and to HHH (Hour).
