      Network-based telemetry systems are increasingly being used to improve the flexibility and longevity of flight test systems. Modern network-based flight test systems utilize large numbers of devices including high-speed network switches, data acquisition devices, recorders, and telemetry interfaces, all of which must be managed in a coordinated fashion. The move to network-based testing provides the ability to build a standards-based System Management interface which can status and control a diverse set of devices. The benefits include the ability to easily tailor System Management tools to support many different styles of user interactions and to quickly integrate new types of devices. While the new capabilities presented by System Management are exciting, the very openness of the system presents challenges to ensure that future growth will be seamlessly supported. This paper will discuss issues encountered while implementing flight test System Management tools for a network-based telemetry system.
    • Technology Trades for Management of Telemetry Network Systems

      The Integrated Network Enhanced Telemetry (iNET) Project established a standards working group to address the integrated management of telemetry network systems and to ensure interoperability among various pieces of equipment. The group has been studying the benefits and drawbacks of various system management technologies with the goal of identifying a set of management interfaces which will provide long-range benefit to a large and diverse telemetry test system. This paper discusses control, configuration, status, performance, and fault management. It addresses these from several viewpoints such as multi-test articles, multi-ranges, and dynamic test environments.
    • TENA in a Telemetry Network System

      Saylor, Kase J.; Malatesta, William A.; Abbott, Ben A.; Southwest Research Institute; Naval Air Systems Command (NAVAIR) (International Foundation for Telemetering, 2008-10)
      The integrated Network Enhanced Telemetry (iNET) and Test and Training Enabling Architecture (TENA) projects are working to understand how TENA will perform in a Telemetry Network System. This paper discusses a demonstration prototype that is being used to investigate the use of TENA across a constrained test environment simulating iNET capabilities. Some of the key elements being evaluated are throughput, latency, memory utilization, memory footprint, and bandwidth. The results of these evaluations will be presented. Additionally, the paper briefly discusses modeling and metadata requirements for TENA and iNET.
