Resilience Capital Partners acquires Systron Donner Inertial

Resilience Capital Partners, a private equity firm that invests in middle-market companies, announced it has acquired Concord, California-headquartered Systron Donner Inertial. As the world’s leading supplier of quartz microelectromechanical systems (QMEMS) used in inertial sensing products that provide precision guidance, navigation and locational solutions, Systron Donner develops products that have been used in everything from business aircraft to fighter jets to the MARS Rover.


“Systron Donner is an important player in an industry that is critical to America’s future economic prosperity, leadership in aviation and national security,” said Steven H. Rosen, co-chief executive officer of Resilience. “Technology and innovation leadership is important for our nation’s future, and Systron Donner has been at the forefront of developing high-performing, made-in-America inertial sensors and systems for more than 50 years.”

Systron Donner’s QMEMS technologies are used in gyroscopes, accelerometers, inertial measurement units and inertial navigation system/GPS products that provide highly precise and reliable stabilization, geo-location, guidance, navigation and flight control solutions for aerospace, marine and land vehicles and systems.

The future for such sensing products is highly promising. The market for inertial navigation systems alone is projected to grow from $9.54 billion in 2017 to $12.26 billion by 2022, a compound annual growth rate of 5.15 percent, according to an analysis by the business forecasting firm Research and Markets.

“Systron Donner’s proprietary technologies, the increasing size of the inertial sensing market and the company’s long history of relationships with a roster of blue-chip customers make this a company with strong potential,” said Rosen. “We look forward to working with the Systron Donner team to maximize this opportunity.”


The continued domestic development and manufacture of products for the aerospace and defense industries is seen as vital, given fears that a decline in American technology leadership could impair national security. Recent analyses, including a whitepaper authored by experts from the Institute for National Strategic Studies and a study prepared by a team assembled by the Office of the Director of National Intelligence and the U.S. Department of Homeland Security, have underscored these concerns.

As a US-based entity and small-business Systron Donner Inertial is uniquely positioned to capitalize on unmet aerospace and defense market needs.
