提出了利用GPS网形的基尼系数对误差分配均匀度的评价,从而评价GPS网形可靠性的方法。网形各点的点位精度通过基线的几何条件定权,洛伦兹曲线利用三次曲线进行拟合,从而构建出网形的基尼系数,并通过算例证明了基尼系数评价网形稳定性的可行性与优越性。
Gini Coefficient is an economic index of the standard of the income. The method of estimating stability of network, based on Gini Coefficient, is given in a special form. It is viable after preparing with the traditional methods of stability estimate.
