    摘要: A synchronous earth satellite typically describes a figure ''''8'''' pattern because the plane of its orbit is generally inclined and/or elliptical. To satisfactorily track this satellite motion, the Fourier components of the same in azimuth and elevation are calculated from the orbit parameters and a partial Fourier series synthesizer is utilized to derive a pair of voltages proportional to desired elevation and azimuth correction signals. The latter are then used to correct the original or normal positioning of the tracking antenna so that the same follows the figure ''''8'''' pattern described by the satellite.
