Study and Application of GPS Height Transformation Based on SST Earth Gravity(EG) Model 基于SST地球重力(EG)场模型的GPS高程转换研究及应用
An Earth gravity field model and the characteristics of gravity anomalies of China sea and its adjacent regions are summarized. 描述了地球重力(EG)场模型和中国海及邻域重力异常的特征。
The shape and perigee of artificial satellite orbits shall continually variate due to caused by the atmospherical drag and the earth gravity. 人造地球卫星的轨道由于大气阻力和地球引力场等因素的摄动,其形状和近地点位置将不断改变。
Expressions of Earth Gravity(EG) Field, Gravity and Gravity Gradient in 3D Cartesian Coordinates System 地球重力(EG)场、重力、重力梯度在三维直角坐标系中的表达式
The aurora display was not caused by the continuing magnetic blasts from Planet X, as auroras are caused by fluctuations in Earth gravity field. 极光的出现并不是来自于X星的持续的磁场轰炸引起的,因为极光是由地球重力(EG)场的波动引起的。
