探讨低阶地球位系数secular variations的一种可能的新方法
On a possible new approach for investigating the secular variations of the low-degree geopotential coefficients
摘要：
本文试图提出一种新的方法来确定地球位势的偶次纬向谐波J_l。将审查某些现有测地SLR卫星的一些开普勒轨道要素的适当线性组合残差的多年时间序列。对于我们不感兴趣的位势部分，应使用CHAMP/GRACE背景参考模型。通过构造，感兴趣的偶次带谐函数的检索值将彼此独立，并且与任何后牛顿特征无关。这样获得的微型模型，随后，可以用来提高后牛顿重力的一些测试的准确性和可靠性，特别强调通过LAGEOS和LAGEOS II的透镜-Thirring效应的测量。
英文摘要：
In this paper we try to suggest a possible novel method to determine some selected even zonal harmonics J_l of the Earth's geopotential. Time series many years long of suitably linearly combined residuals of some Keplerian orbital elements of certain existing geodetic SLR satellites would be examined. A CHAMP/GRACE-only background reference model should be used for the part of the geopotential which we are not interested in. The retrieved values for the even zonal harmonics of interest would be, by construction, independent of each other and of any post-Newtonian features. The so obtained mini-model could, subsequently, be used in order to enhance the accuracy and the reliability of some tests of post-Newtonian gravity, with particular emphasis to the measurement of the Lense-Thirring effect by means of LAGEOS and LAGEOS II.
