An altitude and azimuth angle concurrent driving type solar tracking apparatus, which includes: a worm receiving rotational power through a first end and coupled to a central shaft in a casing; an altitude actuator engaged with the worm; an azimuth actuator engaged with the worm; a diurnal ...
We know that the solar altitude angle is the complementary angle of the solar zenith angle. So the effort is to calculate the zenith angle AOB at point A. This angle can be calculated by using the Law of Cosines: c 2 = a

The horizontal angle measured clockwise between a celestial object and the northern point of the horizon as seen by the observer. Azimuth and altitude are the coordinates used to navigate with respect to the stars. The American Heritage® Student Science Dictionary, Second Edition. Copyright © ...
4/- As the latitude for the grid is not being exactly that of the observer and the true time at the location is not being equal to the zonal time the slide star disk may not give very accurate values of elevation and azimuth angle for the stars within 30 degree of the zenith. However...
time-and-altitude azimuth [¦tīm ən ′al·tə‚tüd ¦az·ə·məth] (navigation) In celestial navigation, the azimuth derived by a computation in which meridian angle, declination, and altitude are parameters, the values of which are either known or assumed. ...
