Spectrum Efficient Technology
Abstract
The SET project risk reduced a ruggedized Ethernet switch for airborne systems in support of the Central Test and Evaluation Investment Program (CTEIP) networked telemetry projects. The ruggedized Ethernet switch addressed CTEIP requirements to fully instrument test aircraft with network enable instrumentation packages to support bi-directional telemetry. The ruggedized switch provides the Ethernet backbone on the aircraft which supports the transport of packetized telemetry data from the onboard instrumentation systems to the telemetry transceiver which transmits the data to the control room. The SET project successfully demonstrated a software tool capable of accurately estimating current and future spectrum needs. The tool accounted for actual versus scheduled utilization of the spectrum and quantified the cost and schedule implications of the loss of needed spectrum. The spectrum efficient metrics tool provides spectrum managers a planning tool and also provides justification data needed to retain spectrum. The SET project also developed an optimized frequency planning tool supporting frequency re-use planning algorithms for telemetry networks and legacy telemetry systems. This planning tool provides next generation spectrum planning tools allowing for dynamic frequency re-allocation. The SET project completed risk reduction on a networked data recorder and data transmission scheme in support of CTEIP networked telemetry projects. The networked data recorder addressed CTEIP requirements for data recording and parametric extraction during flight testing. The networked data recorder was used as the primary data recorder during CTEIP flight tests. The data transmission scheme is designed to minimize the amount and type of data transmitted over the telemetry network, reducing the amount of bandwidth consumed during a test event. This technology enables more efficient use of the RF spectrum by reducing the amount of data transmitted by only transmitting data parameters when changes occur.
