【摘要】 针对我国大地水准面的研究状况，提出了在国家ＧＰＳＢ级网完成之后，利用ＧＰＳ水准、天文重力水准与重力大地水准面３类数据确定我国高精度大地水准面的理论和方法。分析了３类数据的误差传播规律，给出了联合平差模型，并用一模拟网进行了试算更多还原

【Abstract】 According to the situation of geoid stydies in China,this paper presents a theory and method for determination of high accuracy geoid of China by using the three types of data,i.e.GPS leveling,astrogravimetric leveling and gravimetric geoid,after the completion of national B class GPS network.The error propagation rules of the data are analyzed, and the models for combined adjustment are given.Finaly,a computation demonstration is presented using a simulative network.更多还原
