Abstract : The objectives for the Aurora Machine Monitoring and control (MMC) task of DNA Contract DNA 001-85-C-0140 were to design, develop, fabricate, and install a monitor and control system that would significantly increase the amount and quality of the operational information obtained from the Aurora simulator, and to assist the Aurora staff in the operation of the simulator. The accomplishment of these objectives required the design and acquisition of a wide range of hardware and the development of a substantive software package as described below. Initially this task was called the Computer Data Acquisition (CDA) task. Subsequently at the request of Aurora MDC personnel, the task was renamed the Machine Monitoring and Control (MMC) task. At the time the MMC was started, the Aurora simulator was in need of upgrading and refurbishment of a number of its sensor systems. In particular, many of the gas pressure sensors and gauges were either inoperative or inaccurate. The Aurora staff also desired replacement of the high vacuum gauges as well as additional gauges. These requirements were to be addressed in the MMC task. (kr)
