A Chebyshev approximation to the earth's external gravipotential with internally unrestricted mass distribution
ResearchPublished 1965
ResearchPublished 1965
An investigation of the earth's gravitational potential, utilizing spherical harmonic series whose coefficients are found using Chebyshev fitting criterion. The resulting approximations agree with comparable zonal and tesseral harmonic expansions, and the fewer coefficients yield computational advantages.
