Minuteman Digital-Data Transmission System Tests

The high operational reliability required of the communications network for the MINUTEMAN launch-control system made it imperative that extensive testing be performed at various levels of development, prior to installation. Meeting this requirement rests on two types of reliability achievement: one comprises the familiar equipment reliability considerations; the other, emphasized in this paper, relates to the reliable generation, transmission, and demodulation (in the presence of interference) of the digital data signals used for command and status functions.
