NASA introducing reconfigurable networks

Engineers from TSI TelSys Inc. of Columbia, Md., are applying their reconfigurable system technology to enable National Aeronautics and Space Administration (NASA) experts to seamlessly interconnect local- and wide-area terrestrial networks to space communications networks at speeds as fast as 300 Mbit/s.

Traditionally, system hardware functions are hard wired into system board. To change a board, whether adding a new function or correcting an error, a new board must be designed and manufactured.

Instead, the reconfigurable system technology provides a system-level environment and a virtual information processor card "that allows us to make changes to a card at the core logic level after it has been manufactured and installed and without modifying the physical hardware," says TSI TelSys president Jim Chesney.

TSI TelSys is a subcontractor to Lockheed Martin Corp. (formerly Unisys Federal Systems Division) in McLean, Va., in NASA`s Scientific and Engineering Workstation Procurement II program. TSI officials have delivered an initial system to NASA`s Marshall Space Flight Center in Huntsville, Ala.

Reconfigurable systems technology enables continued development of system features and functionality as requirements vary; provides for rapid implementation of new standards and protocols on an "as needed" basis; and protects investments in telemetry, remote sensing, and high-rate data satellite communications equipment. - J.R.
