DEVELOPMENT OF A NETWORK-CENTRIC DATA ACQUISITION, RECORDING, AND TELEMETRY SYSTEMMoodie, Myron; Newton, Todd; Abbott, Ben; Southwest Research Institute (International Foundation for Telemetering, 2007-10)The growth of the Internet and the resulting increasing speeds and decreasing prices of network equipment have spurred much interest in applying networks to flight test applications. However, the best-effort, variable-latency nature of network transport causes challenges that must be addressed to provide reliable data acquisition and timing performance. This paper describes the major issues that must be addressed when designing and implementing real-time networking applications. An overview of a recently implemented large-scale, network-centric data acquisition, recording, and telemetry system for commercial flight test applications provides a real-world example of what is currently achievable.
