telemetry systems offer high frequency response, multiple data channels, the ability to withstand high “g” forces, and adaptable configurations, making it ideal for many aerospace testing applications. Appropriate examples in aerospace testing will be reviewed.
15.00-15.30 Compression-Aware Region of Interest Video Encoding for Full-Motion Video Telemetry and Surveillance
Kurt Hallamasek, VP Engineering, Ampex Data Systems Corporation
High Definition Video sensors are increasingly deployed in airborne platforms to provide near-real time full motion video through a data link or telemetry link. These links are bandwidth-constrained and error prone. An H.264-based method of video encoding is proposed for encoding a context overview and a region of interest in a compression-aware manner. Significant savings in bandwidth can be demonstrated for a given rate distortion. Results are given for MISB EG904 use cases.
15.30-16.00 Build your SIGINT systems through Virtual Instrumentation
Tim Fountain, Market Dev. Mgr Aero & Defense, National Instruments
The ever-increasing waveform, bandwidth and dynamic of today's signals make the production of relevant and timely intelligence for military commanders and national policy-makers. SIGINT (SIGnal INTelligence) is a category of intelligence that includes transmissions associated with communications, radars, and weapons systems. This webcast deals how to perform the acquisition and analysis tasks for SIGINT COTS- based systems.

Modelling & Simulation
10.15-10.45 Modelling and Simulation at System Test – Proceeding and Tools
Frank Westerbuhr, Expert 'System Test and Test Tools', EADS Military Air Systems
At EADS MAS Models and Simulations are in usage within all Projects and over the whole Development Process. They are an important part of our Processes and Tools to safe project costs and to enhance the product quality. Our experiences will be presented iaw. of lessons learned for e.g. Scenario Simulation, Equipment Simulation, Rig Support Equipment, Off- and Online Test Analysis, early User involvement and Rapid Prototyping. Additionally an overview is given about the used tools, which are mainly AIDASS and MATLAB.
10.45-11.15 Simulation, Test and Verification of SHEFEX-2 Hybrid Navigation System
Stephan Theil, Department Head, DLR
In 2010 the German Aerospace Center (DLR) will conduct the second experiment of its hypersonic Sharp Edge Flight Experiment Program SHEFEX-2. The mission will investigate new shapes for launcher or re-entry vehicles with faceted surfaces. A key re-entry technology to demonstrate is hypersonic flight control using steerable canards relying on an accurate hybrid navigation system with multiple sensors. This talk presents the methodology of the hardware-in-the-loop tests of the hybrid navigation system using a dSPACE HIL system. These tests subject the flight hardware to simulated flight and laboratory conditions in three phases to debug the system and prove robustness.
11.15-11.45 From model-based engineering to testing
Sven-Olaf Schulze, Team Leader Aeronautics, Berner & Mattner Systemtechnik GmbH
The presentation focuses on the practical experience in a research project for green aviation on methods and tools using the model-based approach from requirements to verification/validation and test interface. It shows the complexity handled and the lessons learned to manage the content visually in teams until the emulation at the test bench. Using the executable specification, all the requirements and allocated parameters were traded and optimized until the test bench came to life. The trades cover cost, weight, performance and other parameters within one single model to show feasibility and optimize the sub-system within the aircraft system using multidisciplinary interfaces.
11.45-12.15 Real-Time Simulation of generators and electric motors
Jörg Werner, Project Lead, Silver-Atena
In the Aerospace Industry more and more hydraulic systems are replaced by mechantronic systems to save weight and improve reliability. This means that components like generators and electric motors need to be included in the different test-rigs. Instead of using real electric motors/generators it is possible to use a real-time electric motor/generator simulation, which is more flexible and thus shortens the time to market and costs less money. In this technical seminar the different approaches to simulate an electric motor/generator are compared and the advantages/disadvantages of each solution are discussed.
12.15-12.45 From Virtual to Real Aircraft System Integration
Roland Schabenberger, Software Engineer, EADS Military Air Systems
Early in the development phase of an aircraft hardware components are often not available. The effort for hardware integration testing is very high. Therefore in the TALARION project of MAS software models will be tested and integrated on host computers in a representative virtual integration environment. During the development process these models are replaced step by step by real hardware components in test rigs. Actual implementations and the new virtual and real integration environment will be presented.
