TEST CAR PROGRAM

During the period covered by the report, much of the developmental effort was devoted to improving and refining the existing systems. Developments such as a new signal conditioner for the gage sensors, a magnetic pulser for improved speed and distance measurement, and new sensor configurations were aimed at increasing the accuracy and reliability of track measurements. Improvements in overall system performance resulted from the development of special-purpose calibration devices, modifications to existing electronic circuitry, a more extensive use of selective filtering, and use of accelerometers which withstood the hostile environment. Data processing techniques and displays were also modified to make better use of the data being collected and to present it in a convenient form for operating personnel. (Author)
