Profile: Systron Donner Inertial is a supplier of quartz MEMS inertial sensing products and systems, and provide precision system solutions to aerospace, military & commercial aircraft, marine & land vehicular applications. We are an ISO 9001 certified company. Our product line includes inertial measurement units, multi-axis inertial sensing system, and rate sensors. Our inertial measurement units provide the foundation for integration with acquisition code global positioning systems, and system electronics to provide a series of completely self-contained global positioning systems. Our single-axis rate sensors produce a signal output proportional to the rate of rotation of the surface to which attached in a given direction, and they can be used individually for x-axis in multiple units for multi-axis rotational change detection.
