## Theory and Application of the Combined Adjustment of Satellite and Terrestrial Network

• 摘要: 卫星网与地面网联合平差的研究主要包括:(1)卫星系统与地面系统之间的转换模型;(2)联合平差的实施方案;(3)联合平差的误差分析;(4)联合平差程序的研制和实际应用。近几年来,国内外一些学者对联合平差的理论和方法进行了广泛的研究,我们也对上述问题作了较系统的探讨,对有些问题的研究已在1~4中论述过,本文仅对上述问题作必要的补充和综合,从而进一步说明联合平差的有关理论问题和实用意义。

Abstract: This paper is a report of the study on the combined adjustment of satellite and terrestrial network,which is a research project undertaken in recent years.In this paper the following points have been discussed:——the WUS model with seven parameters and model appending VLBI observations.(the former likely makes the deviation of the translation parameters minimum and the latter will be able to keep the scale parameter of the terrestrial network separate from the scale parameter of the satellite network).——the method of the combined adjustment by means of least squares collocation and build-up of observation equations in different coordinate system.——The analyses of the errors in the combined adjustment in which emphasis is placed on the concept of "Influence rate".——A development of the combined adjustment program with multifunction such as the location of the gross errors,estimation of the variance components;the hypothetic test of the transformation parameters and automatic selection of models with appropriate nember of transformation parameters and so on.——The application of the combined adjustment to North-West satellite network and terrestrial network.
