Delta 181 Sensor Module Command Center.

Abstract : An APL-designed sensor module was launched into orbit and performed a number of significant SDI Delta 181 program experiments. Sensor module on-orbit command and control operations involved a network of worldwide facilities called the control complex. A major component was the sensor module command center, which was designed, installed, and operated by APL. This document presents an overview of command center system design. Particular emphasis is given to the hardware design and interface to worldwide assets. Pertinent detail of the Delta 181 control complex and command center mission operations is given to place the design in overall context. The command center design is described within the context of the Delta 181 mission. After completion of the Delta 181 mission, a modified version of the command center was used to successfully support the Delta Star mission in March 1989. Mission control center and network design concepts developed for these programs is being over to ongoing development of similar applications.
