Here is current Progress M-34 EFG vector. EFG - Earth Fixed Greenwich
coordinate system with X axis in the palne of TRUE EARTH EQUATOR (precession
and nutation components are taking into account) at the TIME OF VECTOR and
directed from Earth' mass center to point of crossing of the true equator
and Greenwich prime meridian, Z axis is perpendicular to the true equator
plane and directed from Earth' mass center to the north pole, Y axis
completes system to the right-hand.
