In this paper the computation method of geoid variation with time by repeated level-ling and gravimetry is discussed by the authors. The optimization method of positionalparameters of fictitious point masses is presented. The fictitious point mass method over-comes the disadvantage of stokes integral and collocation. Simulated computation showsthat the computed geoid variation is very accurate.
