AbstractThe Network Command Processing System (NCPS) developed for the National Aeronautics and Space Administration (NASA) Ground Network (GN) stations by the Bendix Field Engineering Corporation (BFEC) is a spacecraft command system utilizing a Multibus/68030 microprocessor. This system was developed and implemented at ground stations worldwide to provide a Project Operations Control Center (POCC) with command capability for support of spacecraft operations such as the LANDSAT, Tracking and Data Relay Satellite and Nimbus-7 spacecraft. The NCPS interacts with the POCC and a local operator to process configuration requests, generate modulated uplink sequences, and inform users of the ground command link status. This paper, which provides an NCPS description, consists of two sections. The first section presents the system functional description and the hardware description. The second section presents software design considerations including the implementation of a flexible and expandable operator interface, maximization of reusable software modules, and validation of BFEC designed development tools.
