Loral Instrumentation has introduced a telemetry system in a rolling cart for aerospace and military applications requiring a portable telemetry system to acquire, analyze, and store real-time data. The portable system features a distributed architecture and dedicated processors that do not “bog down” a central CPU, thus eliminating the risk of lost data.
Loral’s new portable system consists of single or multiple Advanced Decommutation Systems (ADS100s), custom-configured from more than 50 off-the-shelf application modules; a Kennedy 9610 Digital Tape Unit; and one or more Fujitsu 1.6 megabyte removable hard disks, all housed in racks built inside a wheeled cart. A Hewlett Packard Thinkjet printer and a Dotronix monitor sit on top of the cart. The monitor and keyboard, with a 10-foot keyboard cable, can be moved to a nearby flat surface to create data bases and view processed data.
Loral’s portable telemetry system decommutates telemetry streams up to 15 megabits per second; monitors, archives, and simulates data on a MIL-STD-1553 bus, and decommutates the IRIG standard for MIL-STD-1553 data. It processes all data in real time for display and archiving at 540K parameters-per-second processing throughout using 5th-order Engineering Unit conversion as a bench mark. The system time-stamps all or selected data, transfers real-time or archived data to a host computer through a DMA link, and archives raw or processed data to removable hard disks or digital tape. It simulates high-speed telemetry streams with the capability of dynamically changing data in real time.
