TELEMETRY DATA REDUCTION FACILITY, DESIGN TECHNIQUES,
Abstract
The Applied Physics Laboratory has recently completed construction of a Data Processing Facility to provide for processing, for the Bureau of Naval Weapons, a wide variety of types of telemetry and systems data from several weapon system programs, recorded on magnetic tape. This report briefly describes some of the special devices with which this new facility is equipped to increase its flexibility and efficiency. Among them are a tape recorder control patching system, and a station control unit which permits operators of individual stations a broad control of separate-station, inter-station, area, and remotelocation functions. The facility utilizes 58 discriminators located in various stations, for which an automatic calibration system has been constructed to perform a detailed daily check of the linearity of each discriminator. The complete system uses approximately 70 kilowatts of 3-phase AC power. Discussed herein are the means of power distribution as well as a unique power control system that automatically applies power to the start of a work day and provides automatic cut-off under several different conditions. Also, the highly effective and successful ground loop control system utilized here is covered in sufficient detail to aid in the design of similar facilities. (Author)
