Abstract: | In this paper we study the following mixed boundary value problem
where is the reference ellipsoid, and T the disturbing potential. With the help of the variational principles of partial differential equations and the expression
of ellipsoidal harmonic series, we give a linear system related to the coefficients of the ellipsoidal harmonic series. Hence
the solution of the problem can be obtained in the form of ellipsoidal harmonic series, which supplies us an important theoretical
basis for making use of data given by satellite altimetry measurements more efficiently.
