Los Angeles, California (January 11, 2011) – AEi Systems, the world leader in worst
case circuit analysis (WCCA), has completed electrical stress & derating, reliability,
failure mode, and worst case circuit analyses for PerkinElmer’s Rubidium Atomic
Frequency Standard (RAFS), a critical portion of the GPS III satellite program.
The RAFS passed its critical design review with the assistance of AEi Systems.
The Lockheed Martin-led team developing the U.S. Air Force’s next generation Global
Positioning System (GPS III) completed the program’s critical design review on August
20, 2010, two months ahead of schedule, and is now proceeding rapidly in the program’s
manufacturing phase. The first launch of a GPS III satellite, which will provide
significant improvements over current satellites, is scheduled for 2014 from Cape
Canaveral Air Force Station in Florida.
GPS III RAFS program manager, John Vaccaro, said, “AEi Systems is an invaluable
resource. The AEi Systems engineers quickly achieved expert-level knowledge of the
design and operation of our high-performance space-qualified rubidium frequency
standard and helped us close out all remaining component electrical stress and end-of-life
circuit-stability design matters within the required deadlines.”
PerkinElmer Frequency Standards Product Manager, Arnie Shuman, also commented, noting
that “AEi Systems met and exceeded our delivery timeframe and results expectations
and was an asset throughout the entire critical design review process. With the
dedicated effort of the AEi Systems team, we were able to meet our commitments to
ITT, Lockheed Martin and the U.S. Air Force.”
“AEi Systems is very pleased to have been of service and to have participated in
the analysis, modeling, and testing of such an important piece of the GPSIII system,”
added Charles Hymowitz, managing director of AEi Systems. “We look forward to working
on future versions and to continuing our strong relationship with PerkinElmer and
all the other subcontractors involved in this landmark project.”
GPS III will improve position, navigation and timing services and provide advanced
anti-jam capabilities yielding superior system security, accuracy and reliability
for more than 750 million users around the globe. The RAFS is a critical portion
of the GPSIII program because GPS satellite technology is inherently dependent on
the availability of an extremely accurate and highly stable onboard frequency source.
WCCA is performed to improve design reliability and to establish that a product’s
performance has a design capable of meeting its specifications throughout its entire
operational life. In addition to WCCA, AEi Systems specializes in circuit stress
and derating analysis, failure mode effects criticality analysis (FMECA), reliability/mean
time between failures (MTBF) analysis, and SPICE modeling, especially in the area
of power systems and devices for applications in the medical, military, space, nuclear,
and other industries where high reliability is required.
