【摘要】 重力梯度为重力位的二阶导数,可以通过星载梯度仪进行观测。重力场球谐函数系数可以通过正则化方法由重力梯度算出。本文在对正则化方法分析的基础上提出了估计球谐函数系数正则解误差的方法,为我国今后发射重力梯度卫星提供技术准备。更多还原

【Abstract】 Gravity gradient is the second order derivative of gravitational potential, which can be observed by satellite gradiometer. The spherical harmonic coefficients of the gravity field can be obtained from gravity gradients through regularization scheme. Based on the analysis of the regularization scheme, a method to estimate the error of regularization solution is presented in this paper. The results of this paper will provide technical materials for Chinese future satellite gravity mission.更多还原
