| Zusammenfassung |
| Geodetic precession is the largest relativistic effect in Earth rotation. Up to now the
standard procedure was to calculate this effect separately and add it to a purely
Newtonian solution. With our rigorous relativistic model (Klioner et al., 2001),
we are now able to describe Earth rotation for the first time in a consistent way.
We have found that this standard treatment of geodetic precession is not correct.
The inconsistency of the standard treatment leads to errors in all modern theories
of Earth rotation with a magnitude of up to 200 μas when the time span of one
century is considered. Therefore, the consistent treatment of geodetic precession is
indispensable, since the goal accuracy of modern theories of Earth rotation is 1 μas. |
