AFRC has previously investigated the use of Network Based Telemetry. We will be building on that research to enable On-Demand Telemetry. On-Demand Telemetry is a way to only telemeter data that is requested when it is requested by bringing current networking technologies to the flight test world. Through this approach we can plan what data to telemeter at different points throughout a mission and reduce the overall spectrum required. This approach enables the changing of parameter rates on researcher need live through a flight test mission. We will evaluate different approaches of the Publish Subscribe messaging paradigm to what fits the requirements of our range assets, aircraft embedded systems, and operational considerations. We will build up to a lab test. At the end of FY18 we will produce a report with our findings in integrating a lab test and requirements that could lead to a flight system for future testing.
