Engineering Company

AEi Systems is a space and power electronics engineering firm based in the United States that concentrates on circuit, systems and design analysis. AEi Systems specialises in Worst case circuit analysis (WCCA) of critical space-bound circuitry, boards and components, including power supplies and power systems. Such specialized analysis often informs changes and updates to designs that have previously been deemed flight-ready.2 Wikipedia text CC BY-SA 4.0

AEi Systems is a space and power electronics engineering firm based in the United States that concentrates on circuit, systems and design analysis.2

The story

The company's predecessor, Analytical Engineering, Inc., was founded in 1995. The company met with significant early success as the developer of simulation models and performed Worst Case Circuit Analysis on the International Space Station's power bus electronics. A series of satellite projects continued to keep founder Steve Sandler and Analytical Engineering busy, including Tempo, Globalstar, GOES, GPS, MCI, Omegasat and P-81.

In 2002, with the idea of expanding the business and the management team, the businesses of Arizona-based Analytical Engineering, Inc. and a related New York-based company, Analytical Services, Inc., were combined and purchased by AEi Systems, LLC in transactions spearheaded by Charles Hymowitz (an electrical engineer formerly of McDonnell Douglas and Intusoft) and his business partner, Lee Weinberg.

AEi Systems continues to improve its capabilities and to set the standard for performance of Worst Case Circuit Analysis, stress analysis, failure analysis and reliability analysis. AEi Systems has also expanded its digital analysis offerings and capabilities to include performance of in-depth reviews and analyses of the signal integrity and the power integrity of identified circuitry, boards and systems (in addition to Worst Case Digital Analysis).

AEi Systems has senior engineers in several United States cities.
