Abstract:
A sun-tracking apparatus for use with solar-dependent equipment and celestial apparatus, comprising:mounting means;a rotatable polar shaft having a polar axis;a rotatable orbital shaft having a longitudinal axis;a first polar drive means operatively connected to said polar shaft;a second orbital drive means operatively connected to said orbital shaft;means for mounting said second orbital drive means to said polar shaft;said polar axis of said polar shaft and said longitudinal axis of said orbital shaft forming an angle approximately equal to the angle of tilt of the earth's axis;said first drive means rotating said polar shaft at a first rate approximately equal to the rate of rotation of the earth about its axis; said second drive means rotating said orbital shaft at a second rate close to the rate of the orbital revolution of the earth about the sun.
