• Managing Instrumentation Networks

      As traditional data acquisition systems give way to network-based data acquisition systems a new approach to instrumentation configuration, management and analysis is required. Today, most flight test programs are supported by traditional instrumentation systems and software. Pockets of network-based systems exist but are typically entirely new, closed systems. Relatively soon, test articles will emerge with a mixture of equipment. The merger of traditional and networked instrumentation is inevitable. Bridging the gap in software tools is a non-trivial task. Network-based data acquisition systems provide expanded flexibility and capabilities well beyond traditional systems. Yet pre-existing equipment requires traditional configuration and analysis tools. Traditional flight test software alone cannot fully exploit the added benefits gained from such mergers. The need exists for a new type of flight test software that handles existing instrumentation while also providing additional features to manage a network of devices. Network management is new to flight test software but a thoughtful implementation can facilitate easy transition to these modern systems. This paper explores the technologies required to satisfy traditional system configuration as well as the less understood aspects of network management and analysis. Examples of software that meet or exceed these requirements are provided.

      Teletronics Technology Corp. has been involved in the research and development of networked data acquisition systems for use in airborne instrumentation for several years. Recently, TTC successfully applied the advanced technology that was developed during these airborne efforts to a terrestrial application involving Army ground vehicles. The Future Combat Systems Program (FCS) for the U.S. Army recently solicited a networked-based solution to the problem of acquiring real-time data specific to the training of soldiers operating visual targeting systems within Bradley Armored Vehicles and Abrams Battle Tanks. This paper describes the High-Speed Digital Recording system, a network-based data acquisition system designed to allow for the recording of high-resolution (up to 1600x1280) RGB video, user-selected Ethernet packets, along with audio and GPS time information.
