WebFigure 1:: Transformations between ENU and ECEF coordinates. From the figure 1 it follows that the ENU coordinates can be transformed to the [math] (x,y,z) [/math] ECEF by two rotations, where [math]\varphi [/math] and [math]\lambda [/math] are, respectively, the latitude and longitude from the ellipsoid: 1. Earth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Earth and are fixed with respect to the stars. "I" in "ECI" stands for inertial (i.e. "not accelerating"), in contrast to the "Earth-centered - Earth-fixed" (ECEF) frames, which remains fixed with respect to Earth's surface in its rotation, and then rotates with respect to stars. sohela bouaiche
