The inner belt contains a large flux of high energy penetrating protons while the outer belt consists mainly of low energy electrons. The inner belt, therefore, is of considerable importance from a spacemedical point of view since shielding presents a real problem. We discuss again the possible ...
theories and methods of the Earth's gravity field model determination are presented and the Earth's gravity field models established from the multisource gravity data are summarized.The paper mainly focus on the application of the Earth's gravity field model in discipline of surveying and mapping....
