Abstract:Based on the computer algebraic system, we develop the normal gravity formula in series. Then, the function formula of the geocentric latitude at the average value of the normal gravity with respect to the first eccentricity of the ellipsoid is deduced. In addition, it is considered that the formula can be extended to the planets in the solar system; when the first eccentricity of the ellipsoid is assumed to be a variable, we deduce the function formula of the geocentric latitude at the average value of the normal gravity with respect to the first eccentricity of the ellipsoid.
