Abstract : A computer study was made of the affects of guidance data rate and control response time on the accuracy at the target of a controlled bomb. A single guidance system was used, but two control systems were employed, a bang-bang and a continuous system. For the bang-bang system, maximum allowable data rate and control response are one and two seconds, respectively. Inside these limits, no predictable pattern can be established, and each combination must be evaluated. The continuous system provides very good patterns that are highly predictable. Error increases with increases in both data rate and response time. (Author)
