Abstract (in english)
   The explicit form of geoid radius is derived by inverting the geopotential series. Linearization of the radius powers utilizes closeness of the potential and geoid coefficients. Geoid radius errors caused by linearization are as low as 20 mm. Numerical results are given for the gravity model GEM-L2. Differences between the geoidal surface derived on the basis of the present theory and the often adopted surface constructed by means of the Bruns formula lie within +-90cm
