Geodetic Astronomy

has infinite radius

Celestial Sphere

Positions of the stars are recorded by _______

merely specifying angles

astronomic almanac containing tables giving the computed positions of the sun, the planets, and various stars for everyday of a given period

Ephemeris

Horizon System Primary Reference: Secondary Reference: Parameters:

Horizon, Vertical Circle, Azimuth, Altitude

the angular distance measured from the horizon along the vertical circle to the celestial body.

Altitude

angular distance measured clockwise along the horizon from the observer’s meridian to the vertical circle through the body.

Azimuth

Locah Hour Angle Pr: Sr: Parameters

Celestial Equator, Hour Circle, Declination, Local Hour Angle

the angle measured clockwise from the upper branch of the meridian of observation to the meridian of the celestial body

LHA

the angular distance measured from the equator along the hour circle to the celestial body.

Declination

the point at which the sun crosses the celestial equator moving from south to north along the ecliptic

First Point of Aries

great circle on the celestial sphere representing the sun's apparent path during the year,

Ecliptic

–The angle taken counterclockwise along the celestial equator from the First Point of Aries to the hour circle of the star.
