984 – Unique Telemetry Requirements for a Hypersonic Telemetry System 

Paul Cook & Jessie Nokham – Curtiss Wright

With the various hypersonic vehicle developments happening today, there are several unique Telemetry requirements that differ from the ones used in everyday flight test that migrates from the standard products offered in our industry. This paper discusses the unique requirements based on the hypersonic use case, what and whys behind the list, and why are these unique from the airborne perspective and drive new design to full fill the requirement.

467- TRMC Tools for Telemetry

Gene Hudgins and Juana Secondine – TENA

TM often requires operators on location with receive system(s) or at a remote console, resulting in TDY for operators and possibly a shortage of operators to support all scheduled operations. A remote-control capability along with centralized data collection could eliminate existing personnel requirements at both the local system antenna site as well as the control facility, greatly reducing operational costs and providing insight to system status. Established in 2006 under the Test Resource Management Center (TRMC), the Joint Mission Environment Test Capability (JMETC) is a distributed LVC capability using a hybrid network solution for all classifications and cyber. The Test and Training Enabling Architecture (TENA) is the middleware selected for use in JMETC Secret Network (JSN) events and provides for real-time system interoperability, as well as interfacing existing range assets, C4ISR systems, and simulations; fostering reuse of range assets and future software systems. TENA and JMETC, in conjunction with Big Data Analytics (BDA) tools and techniques, allow for the most efficient use of current and future TM range resources via range resource integration, critical to validate system performance in a highly cost-effective manner. This presentation will inform the audience as to the current impact of TENA, JMETC, and BDA on the T&E community; as well as their expected future benefits to the range community and the warfighter.

2913 – BSS – Best Source Selector implementation and performances in a test range

Philippe Klaeyle, Florian Sandoz – SAFRAN Data Systems

Using a BSS in a test range brings multiple benefits such as expanding the area where telemetry can be used, as well as having multiple angles of visibility on the airframe that provides better opportunity to secure a good telemetry reception irrespective of the airframe manoeuvres resulting in some airborne antenna masking towards one of the ground antennas.

Usually the BSS is associated with multiple antennas located somewhat far from each other with the need to carry the telemetry signals to the main station and to have access continuously to the quality of each received signal.

This paper presents the different tasks expected from a BSS. Among others, the BSS needs to compensate for the delays introduced by the distance between the antennas and the associated infrastructure, and to gather information about the quality of the received signals in order to select the one that will result in the best performance. For an easy implementation in a station, the BSS has to interface the various receivers using different interconnection schemes like analog, PCM or direct Ethernet connections.

In addition, we present a validation method using an RF simulator to highlight the performance of a BSS when Data Quality Metric (DQM) is enabled, as well as to compare the performance when the data are provided through a physical digital link from the receivers or through Ethernet. «
