Global gravity field model

WebThe global gravity field model of the Earth is a mathematical model which describes the potential of the gravity field of the Earth in the 3-dimensional space. The terms “gravity field” and “gravitational field” are commonly mixed or used interchangeably. Therefore, we will start with the basic definition of the two terms for the sake ... WebHigh-resolution global gravity field models play a fundamental role in geodesy and Earth sciences, ranging from practical purposes, like precise orbit determination, to scientific applications, like investigations of the density structure of the Earth's interior.
