Recent Progress in Determining the Zonal Harmonics of the Earth's Gravitational Potential

Naturevolume 207pages575576 (1965) | Download Citation



DURING the past year significantly better values have been found for the coefficients of the zonal harmonics in the Earth's gravitational potential. Several authors have given improved sets of values, obtained from analysis of satellite orbits, and the different sets of values agree well, probably because orbits are now available which have a wide variety of inclinations to the equator.
