What Does ECI Stand For?
ECI stands for Earth Centered Inertia Inertials
ECI, or Earth Centered Inertia Inertials, refers to a coordinate system used in orbital mechanics and aerospace applications. This system is centered at the Earth's center of mass and provides a fixed reference frame that allows for the analysis of satellite orbits and dynamics. ECI coordinates remain inertial in nature, minimizing the effects of forces such as Earth's rotation and gravitational perturbations, making them essential for precise modeling and navigation of space objects.
