At last, the ECEF is transformed back to WGS84 which is given by
Coordinates Transformation from ECEF to ECXI System
In order to determine the ECXI coordinates of grid elements, two steps are required: 1) transform the locations and velocities of the transmitter and receiver from the ECEF coordinate system to the ECXI system; 2) conduct a coordinates calculating process for grid elements.
The conversion of velocity from the ECEF to the ENU coordinate system is given as

a) Interested NSFs have a month to register electronically in advance for the ECEF, and can immediately gain access to a customised set of e-resources, such as career preparation tips, career skills workshops and industry insights to prepare them for their career search.
It's typical to make transformation from latitude, longitude, height to ECEF coordinate system.
