The Dryden Flight Research Center (DFRC) Western Aeronautical Test Range (WATR) has the responsibility to acquire and process mission data in support of flight research. System and software engineering services are required to maintain and progress these systems to satisfy dynamic project requirements. The Telemetry/Radar Acquisition and Processing System (TRAPS) is a collection of subsystems which act together to acquire multiple data sources, process the data, distribute the data, and store the data. The information generated in the TRAPS is provided to one or more Mission Control Centers (MCCs). It is the responsibility of the MCCs to present the data on a variety of display devices that are monitored by project and range personnel. The data is used to monitor the status and performance of the research vehicle.
These systems will focus on PC-based platforms, using a version of Microsoft Windows (XP, Server 2003 and others), all networked together. Contractor personnel should be fully proficient in the development and maintenance of software in the Microsoft Visual Studio .Net environment. In the area of programming languages, the primary language is C#, with some development in FORTRAN, Visual Basic and C++.
The WATR Integrated Next Generation Systems (WINGS) will increasingly be involved in network-distributed processes, assets, and customers in support of integrated advanced telemetry projects such as Global Test Range, Network-Enhanced Telemetry (iNET). Some of these assets will be located on the other side of the globe and some may be space-based. Consequently, prototyping advanced capabilities will require the development of new subsystems and interfaces to support communication with entities external to the test range
