SPECIFICATION FOR WEST FORD POINTING PROGRAM

Abstract

A system of computer programs was implemented to support the West Ford project. A general diagram of these programs is given. A particular program of that system is described which is called pointing program. The program accepts, as input, the following information (in punched card form): (1) orbit parameters (defined for a particular time period), (2) site selections (one or more of a small number of predetermined ground sites), and (3) schedule selection(s) (for example, a schedule directing two antennas to a common volume on the belt which gives rise to minimum distance sum). The program computes pointing angles (azimuth and elevation) and predicted range for all the selected sites, for each selected schedule, for approximately a sixhour period at intervals of five seconds or onehalf second. The program also computes expected doppler. The data is put in proper format, written on a magnetic tape, and punched on cards. Each schedule for each site appears on a separate set of output cards, in order that the cards may be used to manufacture TTY tape. (Author)
