  • Description:
    The geopotential of the earth is represented by the potential of a simple layer distributed over the earth’s surface. Density values of this layer for 104 surface elements have been determined from Doppler observations. Computational procedures using this method are presented here. Numerical integration is employed to compute satellite orbits with time sequenced Doppler observations given as input. The geopotential forces acting upon the orbit are described as well as the attraction of the sun and moon, solar radiation pressure, and air drag. The results of the orbit fits are combined in an adjustment to determine the density values of the104 surface elements.
