| Zusammenfassung |
| This study is a sequel to our recent study (Kudryashova et.al., proc. of the Journées
2008) on the potential contribution of new satellite constellations (like revitalized
GLONASS and upcoming GALILEO) to the estimation of nutation rates w.r.t. GPS-only
based nutation rates. The correlation coefficients between nutation rates and some
other parameters could serve as a real measure of the contribution of improved
geometry of an additional (w.r.t. GPS) satellite system. In this investigation we
concentrate on the detailed analysis of correlation coefficients between two sets of
parameters: 1. nutation rates and radiation pressure parameters; 2. nutation rates and polar
motion.
For this purpose two series of nutation rates have been produced. The first series is
based on the GPS observations only. The second series is based on the observations
of two satellite systems: GPS and GLONASS. In order to derive these series we
used simulated observations produced by means of the Bernese v.5.0 software. |
