Acutronic U. S. A. Inc. is a provider of flight motion simulators and inertial guidance test equipment. Rotary motion tables are designed to provide angular rate stimuli acceleration and position to sensors such as gyroscopes accelerometers & inertial platforms. Therefore they are also called rate and positioning tables or inertial guidance test systems & typically comprise one two or three-axis tables for inertial sensor testing. Precision pre-loaded bearings define the axes. A machined tabletop or closed gimbal with a defined hole pattern interfaces with the unit under test (UUT). Slip-rings or twist cables are used to take the UUT signals from the tabletop to the table base. The advanced universal controller Acutrol®3000 controls the tables although for low-cost systems a commercial off the shelf (COTS) controller may be used. Centrifuge systems are designed for the development test evaluation and calibration of accelerometers & a variety of inertial devices. Centrifuges provide an effective solution for the simulation of high-G environments in a laboratory. They support testing of devices such as MEMS-based inertial measurement units (IMUs) quartz or silicon sensors ring laser gyros (RLGs) fiber-optic gyros (FOGs) fuses and crash sensors.
