• PULSE CODE MODULATION TELEMETRY

      Law, Eugene L.; Pacific Missile Test Center (International Foundation for Telemetering, 1982-09)
      This paper discusses the performance of pulse code modulation/frequency modulation (PCM/FM), pulse code modulation/phase modulation (PCM/PM) and phase shift keying (PSK) in the “real-world” of range telemetry. The topics addressed include: 1. Radio frequency (RF) spectra 2. Bit error rate (BER) versus pre-detection signal-to-noise ratio (SNR) 3. Peak carrier deviation 4. Premodulation and receiver predetection filtering 5. PCM codes 6. Magnetic recording The purpose of this paper is to provide the reader with information needed to choose the best modulation method, PCM code, premodulation filter bandwidth and type, receiver settings, and recording method for a particular application.
    • RANGE STANDARDS PANEL DISCUSSION

      Ashley, Carl G.; Pacific Missile Test Center (International Foundation for Telemetering, 1982-09)
      The Telemetry Group (TG) of the Range Commanders Council is the primary means of exchanging telemetry technical and operational information and coordinating and standardizing systems, techniques, methods, and procedures. The TG is concerned with such telemetry gathering instrumentation as airborne sensing devices and modulation and multiplexing equipment. In addition, the group monitors developments in telemetry processing and storage systems and special display devices. The group is also responsible for writing and updating the Telemetry Standards Document and a series of five volumes on Text Methods for Telemetry Systems and Subsystems.
