Summary

Up to 1970, solutions for zonal harmonics have been obtained from observations of satellites with inclination greater than 28°. During 1970, three satellites have been launched with smaller inclinations: Peole, 7010901, with 15°; Dial, 7001701, with 5°; and SAS, 7010701, with 3°. The analysis of their orbital parameters obtained with interferometric observations leads to a set of new condition equations. When added to the Kozai set of equations, they contribute to the determination of zonal harmonics of higher degree, to which orbits of low-inclination satellites are sensitive.
