Digital navigation calculators for assessing the ship’s position by simple operation with builtin programs. Easytounderstand dialogue system telling what input data is required, and what output data is displayed.
Major navigation functions are;
Simple operation with builtin 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 builtin 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.
