    Description / Table of Contents: Introduction -- Notes to Theory and Data -- Gravity field of the Moon -- Magnetic field of the Moon -- Surface topography of the Moon -- Geology and geomorphology of the Moon – a necessary introduction -- Geophysics of the Moon – a necessary introduction -- Atlas of the Moon -- Limits and possibilities of interpretation.
    Abstract: This book presents gravity aspects (gravity disturbance, Marussi tensor, two gravity invariants, their certain ratio, the strike angles, and the virtual deformations) which are computed and evaluated for the Moon, using the recent static global gravity field model (GRGM1200A) to degree and order of 600 in spherical harmonic expansion. The magnetic anomaly model and surface topography (from the LOLA mission) are added. Results are shown for the whole Moon, for its segments around the Moon and as zooms for selected impact craters, maria and catenae; they are shortly interpreted and opened for further selenologic applications. The book contains information about the geology of the Moon, together with basic information about the magnetic field, mapping and topography models.

    Notes: Abstract The correlation between the undulations of the equipotential and topography surface of Venus have been investigated over 16 meridional sections as well as, in the global scale. The correlation is, in general high. However, the figure parameters of the ellipsoids best fitting the surface in question differ significantly. The global features like figures of the best-fitting ellipsoids are mutually strange.

    Notes: Summary Oceanography, seismology, gravimetry, lunar laser ranging (LLR) and satellite observations yield various values of the amplitude of the phase lag of body (solid) tides. These results are discussed, the probable value of δ is lower than 0.3 deg, but a sufficiently accurate value is not yet known.

    Notes: Summary The Banach theorem is applied to the Lagrange planetary equation for the semimajor axis of a geostationary satellite orbit to estimate the stability of near-geostationary satellite orbits. To achieve a graveyard (disposal) orbit, which will not interfere (=cross) the “initial” geostationary orbit, the geostationary semi-major axis ag have to be increased at least by 50 km. Numerical results for a variety of graveyard orbits show that the increase of ag by about 100 km will yield “sufficiently stable” orbits (accounting for the Earth's gravitational perturbations only) during the next 150 years.

    Notes: Summary With the aid of a simplified model, the gravitational effect of the anomalous part of the atmosphere was analysed theoretically and formulae were derived for numerical computation. It was found that under extreme meteorological conditions this effect is of the same order as the present accuracy of absolute gravity observations, i.e. ±100–150 nm s−2. It is, therefore, recommended to reduce these observations to some model of the normal atmosphere by introducing computational corrections.

    Notes: Summary The calibrated variance-covariance matrices of the harmonic geopotential coefficients of the recent combined model JGM 2 has been tested and verified by independent crossover altimetry from TOPEX/Poseidon and ERS 1 using the Latitude Lumped Coefficients in the southern oceans area. Although orbits are not yet available for these missions with other recent models for which error matrices have been released, by comparison with JGM 2 results and field differences we also confirm that the error matrices for the satellite model GRIM 4S4p and the combined data model JGM 3 are also generally valid. Projections of these matrices for a variety of inclinations show that many unused orbits of even moderate altitude (≈ 800 km) will still yield trajectory crossover errors at a level of many tens of centimeters even with the latest orbitgeopotential models.

    Notes: Abstract The geodynamic interpretation of the results of GPS observations among the permanently operating stations which establish the frame for defining and conserving the coordinate system and simultaneously for describing the fundamental tendencies of dynamics in the area represented by them, should be deprived of the effects of geodynamic phenomena, which can be either periodic or short-term (even non-periodic) so that secular changes may be found. Some of these influences are included in scientific processing software, others have to be modelled later. The purpose of this project is to determine the influences of the indirect effect of ocean tides and the direct deformational effect of the atmosphere on the results of GPS observations, performed at stations Pecný (Czech Republic), Wettzell (FRG) and Graz (Austria), and also for the GPS stations of the Central Europe Regional Geodynamic Project (CERGOP) in the region of Central and East Europe. On the basis of analyses and results it is possible to claim that at the present accuracy of GPS observations the influence of ocean loading and atmospheric pressure effects for geodynamic campaigns in the region of the Czech Republic is negligible. For campaigns in larger regions (i.e. Central Europe) atmospheric corrections will have to be applied to height differences. These corrections, however, due to their periodicity have negligible influence on secular changes.
