      CTEIP has launched the integrated Network Enhanced Telemetry (iNET) project to foster advances in networking and telemetry technology to meet emerging needs of major test programs as well as within the Major Range and Test Facility Base’s. This paper describes one objective of the vNET concept demonstration to provide a test vehicle instrumentation network architecture that can support additional capabilities for data access to the test vehicle. Specifically, this paper addresses the expansion of the current concept demonstration with the incorporation of the IEEE- 1588 standard as the basis for a network time distribution mechanism. Near-term network-based data acquisition systems will likely consist of a mix of standard IRIG 106 timekeeping and IEEE- 1588 timekeeping; in this paper we will examine the ramifications of using the two approaches with the same test vehicle instrumentation system.
    • METADATA FOR RANGE TELEMETRY

      Grace, Thomas; Fink, Clay; Naval Air Systems Command; John Hopkins University Applied Physics Laboratory (International Foundation for Telemetering, 2006-10)
      CTEIP has launched the integrated Network Enhanced Telemetry (iNET) project to foster advances in networking and telemetry technology to meet emerging needs of major test programs. This paper describes an approach for providing a unified means of describing telemetry systems. It will describe the motivation and framework for a metadata standard for specifying the components of an instrumented test article, its data and the flow of data through a telemetry system. The paper will also describe how this metadata standard can provide the means for describing different transmission formats for a common test article. The result of the task described by this paper will lead to a standard or set of standards that will optimize the use of commercial technology and tools.
