NETWORK SUPPORT OF TDRSS

Abstract

The Tracking and Data Relay Satellite System (TDRSS) is controlled by a local computer network of nine Digital PDP-11/70s and a Univac 1100/82. Distributed processing of specific software tasks provides for high-speed response to time critical loop support, as well as increased reliability and flexibility of the overall system. Man-machine interface, spacecraft monitor/control and computer failover is supported by the distribution of tasks to specific computers within the network. Altogether, the network support of TDRSS makes possible tremendous increases in capability over conventional satellite ground stations.
