Curtiss-Wright delivers data acquisition flight units for NASA's Orion spacecraft
NewsApril 13, 2017
COLORADO SPRINGS, Co. Curtiss-Wright Defense Solutions officials delivered eight data acquisition flight units for integration into NASA?s Orion spacecraft that is planned for use in the Exploration Mission-1 (EM-1), Orion?s second test flight in space. Curtiss-Wright expects to deliver the ninth and final MnACQ-2000 by the end of June 2017.
The Orion spacecraft is designed to take astronauts beyond low-Earth orbit to destinations such as the Moon and Mars. To support these missions, NASA is developing the SLS rocket to provide the launch capability needed to send astronauts farther into the solar system than ever before.
For the Orion EM-1 flight, Curtiss-Wright supplies its MnACQ-2000 Miniature Network Data Acquisition System, a Fast Ethernet 100BASE-T-based networked encoding unit that processes and delivers packetized instrumentation data to designated network nodes. Each of the nine rugged COTS-based units built for Orion EM-1 includes a radiation tolerant power supply, system management overhead, and the specific signal conditioning modules needed to address the number and type of measurements needed during flight. Two 12-Port Ethernet switches that tie the system together and route the data and video have also been delivered for the Orion EM-1 flight.
Curtiss-Wright began shipments of the MnACQ-2000 units to Lockheed Martin, the prime contractor designing and building the Orion spacecraft, early last year. These units are for use on an engineering model of the Orion EM-1 that was built to enable testing of all of the platform software and the integrated Orion capsule.
Curtiss-Wright also provides eight Pulse Code Modulation (PCM)-based Data Acquisition Units that are used to capture flight data for the first flight of the new SLS rocket. All eight CDAUs for Exploration Mission-1 (EM-1) have been delivered to NASA Glenn Research Center as well as four of eight EM-2 CDAUs to be used as backups for EM-1.
