Lockheed Missiles and Space Company has installed a large-scale Automatic Data Acquisition (ADA) system which ties together the Company's manufacturing facilities located in Van Nuys and Sunnyvale, California. The system includes over 200 Remote Input Stations which collect and transmit Company operating data to a central Data Processing Center. Two RCA 301 EDP Systems are used to record and control the flow of data transmitted to the Data Processing Center. A large capacity RCA 366 Data Disc File is used to store information required to provide up-to-date information in response to inquiries received from remotely located Inquiry Stations. In addition to storage of data on the disk files, the system automatically records all incoming and outgoing data on magnetic tape to be used as input to the Company's conventional off-line business data processing applications.
