A proposed computational method for estimation of orbital elements, drag coefficents and potential field parameters from satellite measurements. I Introduction
A new computational approach for estimating the density of the earth's atmosphere at high altitudes, based on measurements of a satellite's motion through the atmosphere. The problem is formulated as a nonlinear multipoint boundary-value problem that can be solved using quasilinearization and high-speed digital computers. A general machine program has been written in FORTRAN IV, and the results of some illustrative preliminary tests are presented. 22 pp. Ref.
