Abstract The Parker Solar Probe is a spacecraft designed to study the Sun's corona from
inside. It is providing unprecedented detailed information on the density and composition of …

Mean orbital elements estimation for geostationary (GEO) satellites is important for related
studies, including station-keeping, rendezvous and end-of-life disposal. With increasingly …

Uncertainties in the satellite world lines lead to dominant positioning errors. In the present
work, using the approach presented in Puchades and Sáez (Astrophys. Space Sci. 352, 307 …

The scope of this thesis is the investigation of Gravity Field Recovery (GFR) from GRACE
(Gravity Recovery And Climate Experiment) satellite observation data. The processing from …

One of geodesy's main tasks is to determine the gravity field of the Earth. High precision
clocks have the potential to provide a new tool in a global determination of the Earth's …

Geodesy, a science that is in our modern understanding a combination of physics, applied
mathematics, and engineering, is concerned with the description and measurement of the …

Classical planetary ephemeris construction comprises three major steps which are to be
performed iteratively: numerical integration of coupled equations of motion of a multi-body …
