Abstract : Simple analytical relationships between geopotential Hpsi and geometric altitude Zpsi for various latitudes psi are presented with the required constants for relating Hpsi to Z, and Zpsi to H at each of eight latitudes 0, 15, 30, 45, 60, 75, 90 deg., and at the reference latitude R equal to 45 deg. 32 ft. 33 in. which latitude corresponds to the standard sealevel gravity, 9.80665 m/sq.sec. Values of HR(Z) were computed for geometric altitudes between 0 and 10,000 km: values of ZR(H) were computed for the equivalent range of geopotentials, between 0 and 3900 standard geopotential kilometers (km'). Computed values of Zpsi and Hpsi for the other latitudes are presented as differences (Zpsi  ZR) and (Hpsi  HR) as functions of both argument pairs HR(Z) and ZR(H) are compared with the corresponding values from the U.S. Standard Atmosphere HS(Z) and ZS(H). These comparisons show the difference (HS  HR) to be 33 meters at ZR = 700 km, while the difference (ZS  ZR) is shown to be 55 meters at the corresponding value of HR = 630 km'. (Author)
