      The goals of TCAS were to recommend a Telemetry Integrated Processing System (TIPS) that will improve SAMTEC mission support, increase flexibility and modularity of the system, and provide a system that is more easily operated by the range operations personnel with an associated reduction in overall operating cost. SAMTEC has completed the conceptual phase of the classical system life cycle. The validation phase is now well underway and the development phase is expected to start early in the calendar year 1975. The Integrated Telemetry System was derived utilizing the fundamentals of good engineering practices, common sense, and very extensive analysis. The resultant system should satisfy the goals of improved support, flexibility and modularity, and should provide at least a 20 to 40 percent reduction in the current telemetry processing expenditures.
    • Simulation of PCM Data Utilizing a General Purpose Computer

      Due to the increased complexity and capabilities of modern missile telemetry systems, it has become increasingly difficult to provide an effective yet flexible simulation capability for the verification and validation of PCM decommutation systems. Control Data Corporation, under contract with the Space and Missile Test Center (SAMTEC) at Vandenberg Air Force Base, California, recently completed the development of a powerful and flexible simulation system utilizing a CDC 3300 computer. This Telemetry Decom Validation System (TDVS) now allows personnel to develop a simulated PCM data stream using a telemetry-oriented compiler to generate telemetry instructions. The compiled program can then be executed in a microprogrammable processor which generates the defined PCM stream through the interpretation of the specially designed instruction set output by the compiler. Data can be simulated at rates up to 2 megabits using any of the seven IRIG code conventions or Miller Code.
    • Use of Pseudo-Random PCM Tape Signatures for Telemetry Ground Station Validation

      Schoeck, K. O.; Pickett, R. B.; Vandenberg Air Force Base (International Foundation for Telemetering, 1974-10)
      This paper describes an improved tape recorder signature using pseudorandom PCM data. The use of the signature for telemetry ground station validation is discussed. Advantages over other techniques in common use are shown.
