A robust approach to global problems in physical geodesy

Abstract. We present a new 180th degree and order model of and order L = 40 (Sjogren et al., 1997), instead of L = 90, as the Venus gravity field directly derived from line of sight suggested by sensitivity studies relative to the cycle 4 Magellan residual Doppler data instead of usual line of sight Magellan orbits. This lower threshold also has the advantage residual acceleration data. We discuss the influence of the a to enhance the signal-to-noise ratio in the Doppler residuals. priori covariance matrices on the deconvolution process, and The second major difference is that we directly processed the compare our results with previous solutions.

Given the broad area of this review: “geodetic theory”, its material has been selected to cover as best as possible the work done in the last four years on basic ideas and methods, recognizing the fact that contemporary geodesy is a discipline with fast‐expanding and, therefore, rather fuzzy boundaries. For this very reason, a non‐too‐subtle selection criterion has been adopted, to avoid ending with an excessively long list of references. By and large, articles presenting mostly quantitative results, or outlining research plans and policies, or hardware developments, have been excluded, particularly those that clearly belong in another section of this Report. Those dedicated mostly to discussing basic concepts, or describing in detail the theories behind various methods, were chosen. The material has been arranged according to one classification scheme (others exist), which, while not being perfectly adequate for all the publications surveyed, may help the reader find those he might be interested in without too much difficulty.
