Spirent Federal GPS Simulator Selected By Honeywell For NASA's Orion
Yorba Linda CA (SPX) Jul 29, 2008 Spirent Federal Systems has announced that Honeywell has selected a Spirent GPS/Inertial simulator to develop, integrate and verify the navigation system for NASA's Orion project. The Spirent simulator includes comprehensive modeling of the space environment and will provide multiple radio frequency (RF) outputs, allowing multiple antenna locations to be simulated. In addition, the system provided for the Orion project will include multiple SimINERTIAL units-Spirent Inertial interfaces that provide Honeywell engineers the capability of emulating Inertial sensor output while simultaneously simulating GPS RF signals. The Orion crew capsule is part of NASA's Constellation Program, which is developing a new human space transportation system that will send explorers to the International Space Station, the moon and beyond in coming decades. The first crewed mission of the Ares I rocket and Orion spacecraft is scheduled for spring 2015. Lockheed Martin serves as the prime contractor to NASA to build the Orion crew exploration vehicle and is responsible for design, development, testing and evaluation. Honeywell is the subcontractor responsible for avionics, including navigation, mission hardware and software, and flight control systems. "Spirent's simulators with SimINERTIAL make controlled, repeatable testing of integrated GPS and Inertial systems an easily-obtained reality," commented Ellen Hall, President of Spirent Federal. "NASA is using the latest technology available to create Orion, and we are pleased our products have been chosen by Honeywell for this important enterprise."

San Diego State University Improves MEMS Accelerometer Tunability
San Diego CA (SPX) Jul 16, 2008Researchers at San Diego State University have developed a new concept for improving MEMS accelerometer tunability. This method can increase wide-band tunability with ranges much larger than current practice, a significant improvement from the previously accepted 5-10%. |
