The Pacific Missile Range System which inputs data to the IBM 7090 Computer at 20 samplessec consists of 1 Cotar which outputs direction cosines alpha and beta, 2 ANFPS-16 radar slaved to the Cotar and which outputs range only, and 3 a second ANFPS-16 radar free to skin-track and output polar coordinate data, becoming another source of input to the computer. A fourth source of data is the Missile Tracking Radar which outputs raw polar data at the rate of 8.123 samplessec. The single system chosen to control destruct computation and impact prediction is based on data quality as determined by comparing rates of change in position and velocity differences with predicted standards. This choice is also influenced by ranking input systems based on their respective inherent reliabilities. Computer output consists of predicted missile impact location, present position, velocity, acceleration displayed at a remote location. The same output and all raw input data are recorded on tape for postflight usage.
