Earth Gravitational Model

The Earth Gravitational Model is a detailed representation of Earth's gravity field, describing how gravity varies across different locations. Since Earth's mass isn't perfectly uniform—due to mountains, ocean trenches, and varying densities—gravity strengths differ slightly from place to place. These models use advanced measurements and mathematical data to map these variations precisely. They are essential for applications like satellite navigation, geophysical research, and understanding Earth's interior. In essence, the Earth Gravitational Model provides an accurate "gravity map" that reflects the planet's complex and uneven mass distribution.
