Go to ITC/USA event

SwRI will be exhibiting at ITC/USA, Booth No. 708 at Renaissance Glendale Hotel & Spa in Glendale.

SwRI is currently developing real-time network-centric solutions for airborne, ground tactical vehicle, automotive, smart grid, and space applications and has extensive experience with standards and technologies such as MDL, DAR, iNET/TmNS, IENA, XidML, TMATS, Constraints, IPv4/v6, Multicast, SNMP, XML, IEEE-1588, CCSDS, TENA, and Spacewire. We also have extensive experience developing network-based flight test systems for commercial and military aircraft. We led the standards development for the iNET program (now IRIG 106 Chapters 21-28 TmNS) and are currently leading the integration of the initial iNET demonstration system.  SwRI uses multidisciplinary approaches to solve problems for a variety of government and industry clients.

Come listen to our speakers in Sessions 10, 13, and 19.

Tuesday, November 6th

3:30 – 5:30 p.m., Aurora C, Session 10: Image and Video I

3:30 p.m. 18-10-01 “Obtaining Measurement Data Using Cockpit Video Cameras,” Hakima Ibaroudene, Myron Moodie, and Ben Abbott

Rather than classic data bus-based acquisition and extraction, we can use cockpit video cameras to extract measurements. These technologies can reduce installation costs and complexity, minimize aircraft modification to obtain parameter data and may be sufficient for some quick-turn, limited-scope flight test operations. This paper explores the challenges and possible approaches for extracting measurements from video imagery of cockpit displays and provides an in-depth case study of a portable system designed to accomplish this task.

Wednesday, November 7th

10:30 a.m. – 12:00 p.m. Aurora C, Session 13: Software Systems & Tools II

11:10 a.m. 18-13-03 “Introducing TACL - A Proposal for a New Standard T&E Constraint Language,” Jakub Moskal (VIStology, Inc.), Austin Whittington, Mieczyslaw Kokar (VIStology, Inc.), and Ben Abbott 

It is expected that XML-based languages for configuring telemetry systems like MDL and TMATS will eventually replace their non-XML predecessors, but despite its numerous benefits, XML does not solve all the related problems. In particular, it cannot harness the complexity of constraints that may pertain to vendor hardware or to express system-level constraints that span across entire networks of devices. In this paper we present TACL, a T&E extension to W3C Shape Constraints Language (SHACL), for formulating constraints on configurations represented in MDL and TMATS, independently of any configuration software. TACL introduces high-level components that help to form constraints close to the user's intent and less concerned with the low-level syntax details. It exhibits much better resilience to changes in the XML schemas than the languages that refer directly to the XML trees. A proof-of-concept TACL engine has been successfully developed and applied to MDL/TACL configurations.

11:30 a.m. 18-13-04 “Current and Future Developments in Flight Test Configuration Techniques,” Austin J Whittington et al.

As technologies like network-based telemetry and standardized configuration languages begin to see wider adoption within the flight test community, novel techniques exploring the new possibilities they provide are also developed. This paper reviews a subset of these techniques, including successful use in commercial flight tests, focusing on the concepts of constraints and their application in the field — specifically their use in helping users to create correct-by-construction configurations. We then explore ongoing efforts with the Air Force and DARPA to extend these techniques into constraint satisfaction and real-time adaptation, providing the ability to create and adapt configurations to match (possibly changing) test requirements.

2:00 – 4:20 p.m., Cira C, Session 19: Telemetry Networks III

2:20 p.m. 18-19-02 “Accelerating Standards Compliant TmNS Radio Implementations,” Todd Newton and Wayne Timme

IRIG 106-17 defines interoperable two-way network telemetry interfaces for the wired, as well as the dynamic, TDMA air interface. While the air interface is based on the familiar SOQPSK-TG waveform, a TmNS-based radio contains a dynamic TDMA MAC regulated by Link Management through the use of RFNMs. This paper illustrates the TmNS-based radio aspects of the IRIG standard by describing our experience utilizing a two-track approach for accelerated TmNS-compliant radio development. We have divided the architecture by engineering discipline lines (Communications vs. Computer Engineering). Doing so allowed us to accelerate the design, simulation, and test tasks while using a common code base across various transceiver implementations. This discussion includes a description of the software modules that provide TmNS interfaces for standards-compliant radio functionality such as the TDMA MAC, RFNM processing, system management, and MDL configuration as well as system-level integration testing.
