Improved Methods for Computing Drag Corrected Missile Impact Predictions in Real Time,
Abstract
During missile flight tests at White Sands Missile Range (WSMR), position data on the current status of the missile is transmitted 20 times per second from radar sites to a Univac 1108 computer. Consecutive pairs of such data are averaged 10 times per second and computations for plotting displays such as current position, range verses altitude, or impact prediction are based upon this averaged data. In the event that a missile veers from its planned trajectory, it will be necessary to determine thrust to prevent the missile from impacting in a populated area. For this reason, the Range Safety Officer (RSO) requires that for each computational cycle (10 per second) an instantaneous impact prediction (IIP) of the missile be computed. This point is the intersection of the missile trajectory, should thrust be terminated, with the Clarke Spheroid (of 1866) model of the Earth at an altitude of 4000 feet. (Author)
