What Does EFCS Stand For?

EFCS stands for Earth Fixed Coordinate System

The Earth Fixed Coordinate System (EFCS) is a geodetic framework that provides a stable reference for defining positions on the Earth's surface. It is centered at the Earth's center of mass and aligned with the Earth's rotation, ensuring that coordinates remain constant relative to the Earth's surface. The EFCS is essential for applications in navigation, mapping, and geospatial analysis, as it enables precise localization and movement tracking in relation to the Earth's features.
