| 摘 要： | 本文将整体大地测量各类观测方程中作为随机信号的重力场参数（ΔN，ξ，η）均表达为重力异常Δg的泛函，又引入Δg的B样条函数并以样条系数C_(11)作待定参数，提出一种整体大地测量的确定性参数模型，给出了相应系数矩阵的表达式和算法，最后对该模型的求解问题作了说明。

| Abstract: | :
This paper presents a deterministic approach to integrated geodesy. The gravity field parameters appearing in observation equations for integrated geodesy, such as deflection of the vertical , and geoidal height N, are expressed as the functionals of gravity anomaly g, and then B-spline functions of g are introduced into the equations in which the coefficients of the splines, Cij, are taken as the unknown parameters. The detail expressions for the corresponding coefficients of observation equations in this ap proach are derived. Finally, remarks on deterministic model for integrated geodesy and on its solution are given briefly. |
