Abstract
Problem of selecting primary parameters has been discussed. Primaries should be defined uniquely, as well as, physically. Since no unique definition for semimajor axis exists, it should be replaced by the geoidal geopotential valueW 0 or by the geopotential scale factorR 0 =GM/W 0, geocentric gravitational constantGM be also primary parameter. Current best estimates of some parameters are given numerically.
