Systron Donner Inertial is Now EMCORE
For more than five decades, the Systron Donner name has been associated with innovation, precision and trusted performance in inertial sensing. From pioneering Quartz MEMS technology to supporting some of the world’s most demanding aerospace, defense and commercial applications, Systron Donner built a legacy of engineering excellence. That legacy continues today as EMCORE.

QUARTS MEMS ADVANTAGES
Quartz MEMS Technology covers the Inertial Sensor tactical grade market needs better than spinning mass gyros, ring laser gyros, fiber optic gyros and silicon gyros.
EMCORE acquired Systron Donner Inertial in 2019, bringing together SDI’s industry-leading Quartz MEMS technology and decades of inertial expertise with EMCORE’s expanding portfolio of advanced navigation solutions.
Today, the products and technologies historically associated with Systron Donner (including QRS® gyroscopes, Q-Flex® accelerometers, SDI® inertial measurement units and advanced inertial navigation systems) continue under the EMCORE brand. They are supported by the same commitment to precision, reliability and performance that customers have trusted for generations.
