Abstract

An attempt is made to reduce the time required in computing planetary and lunar positions ielsen and Martin A. Krop. May 61, 26p. incl. tables. (Contract AF 33(616)6638, Proj. 7041) (ARL-46, Suppl. to WADD TR 60-118, AD-247 127) Unclassified report DESCRIPTORS: *Programming, Moon, Planets, *Digital computers, *Space flight, Astrophys ics, Preparation, Astronomical data, *Celes tial mechanics. An attempt is made to reduce the time required in computing planetary and lunar positions data, and to improve the program where possible. An option was evolved which allows the omission of the determination of the Moon's velocity (if not required) at a considerable savings in computer time. (Author)
