Then the periodic properties of geocenter motion in the x, y, z components are summarized. considering the statistical precision of the gps observations, the geometrical distribution of gps stations and their physical stablility, a new method to determine the parameters of geocenter motion is studied and analyzed. in order to have a better understanding of its effect on the height datum origin, the rule of geocenter motion in the horizontal and vertical components are also analyzed and some useful conclusions are drawn
提出了將譜分析與抗差估計相結合的抗差譜分析方法，並用該方法分析了地心運動時間序列的主要周期特性；為合理地確定地心運動參數，詳細研究與分析了一種新的定權方法對求解地心運動參數的作用，該方法充分利用了gps觀測量的統計精度、點位的幾何分佈以及物理穩定性；為了明確地心運動導致的高程基準的變化，分析了地心運動對地面點的水平分量和垂直分量的影響規律。
