TAMAYA Navigation Calculator 〈NC-2200〉

The NC-2200 is a navigation calculator capable of performing complicated navigation calculation and astro-navigation calculation, with speed and accuracy.  Navigation calculation is a means of determining the position of one’s vessel, by sighting a celestial body in the open sea where land is not visible.

 

The vertical angle between a celestial body in the sky and the horizon can be measured using a sextant, and based on this angle information, one can determine the position of vessel on Earth, in terms of latitude and longitude.  Also, based on the latitude and longitude of point of departure, and the latitude and longitude of point of arrival, course and distance of one’s path to be taken can be calculated.
