A Determination of the Coefficient J of the Second Harmonic in the Earth's Gravitational Potential from the Orbit of Satellite 1958β2
Abstract
From the secular changes in the longitude of the node and the argument of the perigee, the coefficient J in the gravitational potential function ? was determined to be (1.6232±.0005)×10-3. If the bounding equigeopotential surface of the earth is assumed to be an ellipsoid of revolution, this value of J implies a flattening ƒ of 1/298.32±.05.
