Scientific paper
Progress in determining the earth's gravitational field during the 1970s is briefly outlined, and an attempt is made to assess the accuracy of current geoid maps and sets of harmonic coefficients. These are exemplified in the latest models derived at the Goddard Space Flight Center. The harmonic coefficients of order 14, 15, and 30 in the Goddard Earth Model 10B are compared with values obtained independently by analysis of resonant orbits; the results suggest that the values in GEM 10B are realistic for these orders and presumably others. It is determined that the accuracy of geoid maps is now approaching 1 m.
