Abstract
Coefficients of the second, third, fourth, and fifth harmonics of the earth gravitational finld are determined from analysis of motions of three artificial satellites, 1958 ,32, 1959 , and 1959 Ll, as follows: A ,/a = (1.62329+0.00004) X 10-2, A /a = (9.3+0.2) X 10-0, A 3/O, = (2.29+0.02) X 10-0, A o/a,0 = (2.3+0.2) X 10- .
