On The Move, Interactive Telemetry Data Acquisition System for the Multiple Launch Rocket System (MLRS)Kirkpatrick, Charles R.; Tuncay, A. Ayban; Inter-Coastal Electronics (International Foundation for Telemetering, 1993-10)This paper describes the Launcher Instrumentation and Data Acquisition System (LIDAS) that has been developed for real-time monitoring and simultaneous recording of a diverse set of data buses on a moving MLRS launcher. The launcher onboard instrumentation consists of a central Bus Data Conversion Module (BDCM) and several specialized, intelligent "break-in" boxes. The break-in boxes collect and tag the data by using the IRIG-B standard time-code, and transfer them to the BDCM using a unique asynchronous scheme. The BDCM is built around an Intel 80960CA processor board in a VME bus environment. It coordinates all the data traffic and also stores selected data to an onboard Flash ROM data storage unit. The data from different MLRS buses are combined into a 1 megabits per second RS4-22 serial stream and telemetered to a ground station, where the user interface is provided through an IBM PC/AT type computer with touch-screen controls. The developed PC software offers several data monitoring options with engineering-unit conversions and allows simultaneous recording on a hard-disk. Because of its interactive capabilities, the system is also well suited for personnel training.
Uplink/Downlink Real-Time Casualty Assessment Data Acquisition System for U. S. Army Aviation ApplicationsKirkpatrick, Charles R.; Banks, Keith A.; Inter-Coastal Electronics, Inc. (International Foundation for Telemetering, 1993-10)The On-board Data Interface Module (ODIM) was developed specifically to provide real-time casualty assessment telemetry data for the training environment on the instrumented range system at the U. S. Army National Training Center (NTC) located at Ft. Irwin, California. Real-time data acquisition and telemetry systems, such as the ODIM, which enhance the feed back capabilities of fielded training systems are becoming increasingly important to the Department of Defense in these times of shrinking defense budgets and decreasing global stability. The ODIM is designed to combine, process and transmit data from the AH-64 (Apache) 1553 data bus, the Aircraft Survivability Equipment (ASE) threat warnings, the on-board training system laser belt, cockpit kill indicators, and status data. The ODIM also downlinks the stored data though the Micro-B transceiver on the AH-64A. For the application at the NTC, the ODIM looks for very specific data from the AH-64 and the MILES/AGES II system. However, the ODIM is programmable to collect any of the data available from these systems. The uplink/ downlink available through the Micro-B transceiver allows the user access to the ODIM's features even from a remote location.
