    The global and local correlation between the Venus gravity field and its topography (1992)
    Springer
    Earth, moon and planets 57 (1992), S. 123-138 
    Details

    Topics: Geosciences , Physics
    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.

    Tidal friction. Secular variations of the inclination and eccentricity of the Moon's orbit (1985)
    Springer
    Studia geophysica et geodaetica 29 (1985), S. 319-325 
    Details
    ISSN: 1573-1626

    Topics: Architecture, Civil Engineering, Surveying , Geosciences , Physics
    Description / Table of Contents: Summary The computation of the secular variation of the inclination and eccentricity of the Moon's orbit due to tidal forces is revised. Also the effect of the Earth's ellipticity, which amounts to 10−6 to 10−5 of the value for the spherical earth, is estimated and found to be negligible. The results agree well with the computations of Kaula [7], as opposed to MacDonald's results [8] which display an order-of-magnitude difference in the variation of the eccentricity, apparently due to a printing error. Finally, solutions are presented for various values of the dissipation factor.

    Notes: Summary The geopotential scale factor R 0 =GM/W 0 has been determined on the basis of satellite altimetry as R 0=(6 363 672·5±0·3) m and/or the geopotential value on the geoid W 0 =(62 636 256·5±3) m 2 s −2 . It has been stated that R 0 and/or W 0 is independent of the tidal distortion of surface W=W 0 due to the zero frequency tide.

    Tidal friction — on the phase lag of body tides (1992)
    Springer
    Studia geophysica et geodaetica 36 (1992), S. 302-306 
    Details
    ISSN: 1573-1626

    Topics: Architecture, Civil Engineering, Surveying , Geosciences , Physics
    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.

    Investigation of the instability of graveyard orbits due to the earth's gravitational perturbations (1992)
    Springer
    Studia geophysica et geodaetica 36 (1992), S. 297-301 
    Details
    ISSN: 1573-1626
    Source: Springer Online Journal Archives 1860-2000
    Topics: Architecture, Civil Engineering, Surveying , Geosciences , Physics
    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.

    Effect of the anomalous part of the atmosphere on the observed acceleration of gravity (1981)
    Springer
    Studia geophysica et geodaetica 25 (1981), S. 321-331 
    Details
    ISSN: 1573-1626
    Source: Springer Online Journal Archives 1860-2000
    Topics: Architecture, Civil Engineering, Surveying , Geosciences , Physics
    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.

    Accuracy assessments of recent earth gravity models using crossover altimetry (1996)

    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.
