• Now the 2d precision of spatial points is very great , but because by usual correlation fitting method we can transfer gps ellipsoidal height into normal height of the local geoid is considered as mathematical curve plane , it is not conform the fact of mountainous districts so the precision of elevation is so small that it is not satisfied with the requirement of leveling
  目前，地面点的平面位置确定精度已相当高，但高程精度始终未能达到水准测量的要求，因为将gps大地高转化为水准正常高的拟合推估方法是将局部大地水准面视为数学曲面，常常与实际情况差异较大(特别在西部山区差异更大) 。
• 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
  提出了将谱分析与抗差估计相结合的抗差谱分析方法，并用该方法分析了地心运动时间序列的主要周期特性；为合理地确定地心运动参数，详细研究与分析了一种新的定权方法对求解地心运动参数的作用，该方法充分利用了gps观测量的统计精度、点位的几何分布以及物理稳定性；为了明确地心运动导致的高程基准的变化，分析了地心运动对地面点的水平分量和垂直分量的影响规律。
