computed altitude

[kəm′pyüd·əd ′al·tə‚tüd] (navigation) In celestial navigation, tabulated altitude interpolated for increments of latitude, declination, or hour angle; if no interpolation is required, the tabulated altitude and computed altitude are identical. Altitude determined by computation, table, mechanical computer, or graphics, particularly such an altitude of the center of a celestial body measured as an arc on a vertical circle of the celestial sphere from the celestial horizon. Also known as calculated altitude.

computed altitude

i. The indicated altitude corrected for installation and instrument errors. Also called calibrated altitude.
ii. A mathematical computation of the correct celestial altitude of a body at a specific geographic position, for a given date and time. This method helps the navigators quickly find a specific celestial body. Computed altitude is represented by the symbol H_C.
