  • Modern radiometric observations of planets, beginning in 1961, make it possible to determine and improve a broad set of astronomical constants from the value of the astronomical unit (AU) to parameters of PPN formalism. Three main factors that influence the progress in the determination of astronomical constants { 1) reductions of the observational data, 2) dynamical models of planet motion, 3) observational data themselves { are demonstrated in this paper. The reduction of the measurements… CONTINUE READING
