Satellite geodesy: Methods

摘要: General Theory. Analytic solutions for the motion of a near-earth satellite are practical importance orbit prediction and establishment reference orbits I (intermediaries) minimizing perturbations from which geodetic information is extracted. The best known ones currently in use at various computing laboratories those Brouwer Vinti. Bonavito et al. [1969] favor Vinti's method because its apparently better speed accuracy. However, this preference has been questioned by Break- well Vagners [1970], who claim that it possible to choose initial conditions generation keep errors within acceptable bounds. Vinti solution generalized hold triaxially ellipsoidal coordinates [Madden, 1970] so equatorial ellipticity can be made part potential. Deprit Rom [1970] have refined Brouwer's higher orders oblateness application Lie transforms development requisite literal expansions on computer. A new intermediary received much favorable attention ability generate higher-order terms relatively simple fashion Aksnes' [Garfinkel Aksnes, 1970].
