CCS is the culmination of a massive reengineering of both the flight and ground system begun in February 1995 to improve Hubble's overall performance and drastically reduce the cost of operations and systems maintenance. This effort, called Vision 2000, goes well beyond replacing outdated software and hardware. It streamlines the functional flow, eliminates redundant systems and provides the operators and spacecraft engineers with a user-friendly interface. Architectural complexity is greatly reduced by consolidating the functions of the five original systems of spacecraft control, analysis, data management, command management and subsystem calibration into a single system. CCS is very portable.
Users can customize their string's databases to suit their particular application.
Some of the advanced performance features of CCS are identified below. At all times, controllers have instant access to six months of telemetry data, stored either on-line or in data warehouse. CCS provides approximately 300 users concurrent access to Hubble Space Telescope data via an advanced, interactive graph-ical interface to perform monitoring and analysis. The operators can obtain visual displays of any requested telemetry, produce graphs and perform analysis on the data in near real-time at the consoles. Shortly after launch, this team will prepare Hubble for the on-orbit service call.
