Abstract : The present equipment is now showing 192 points on the tracks of 4 satellites with periods of up to 11 days, and data-storage capacity is suitable for over 11 days of future-orbital information. A revision to 128 points on the tracks of 6 satellites with the 11-day time base is possible using the data-storage system provided. Display of an intensified spot for satellite position and a 3-decimal-digit readout of object number or ALTITUDE IS INCLUDED. Techniques used to produce the display include: (1) Input data on punchedpaper tape; (2) High-access-speed storage on a magnetic drum; (3) Arithmatic operations performed in Plug-In Units designed in 8-bit modules; (4) Satellite position and track display on a magnetically-deflected, 21-in, cathode-ray tube; and (5) Light Gun triggered by the presence of an illuminated point on the scope.
