In many targeting and tracking applications the local East, North, Up (ENU) Cartesian coordinate system is far more intuitive and practical than ECEF or Geodetic coordinates. The local ENU coordinates are formed from a plane tangent to the Earth's surface fixed to a specific location and hence it is sometimes known as a "Local Tangent" or "local geodetic" plane. By convention the east axis is labeled , the north and the up .

WebFor orbital dynamics, the time doesn't really enter into the conversion between ECEF and LLA. That is only used to determine where the object in orbit is at that point in time (typically in ECEF). Also, the velocity vector changes over time as the object orbits the earth, but that doesn't have an impact on the conversion either. Share
