Miniature MEMS Quartz Inertial Measurement Unit (IMU) Ideal For Embedded Applications
Light Weight, Low Power Consumption and Small Form Factor Creates Versatile System Solution
Concord, Calif. – June 7, 2004 - BEI Systron Donner Inertial Division (SDID), a division of BEI Technologies, Inc., has introduced a new, miniature MEMS Quartz Inertial Measurement Unit (IMU) utilizing solid-state quartz MEMS inertial rate sensors and silicon MEMS accelerometers. In response to today’s requirements for a small size, moderate performance IMU, the new Model MMQ50 can be incorporated into either stabilization or guidance and control applications in missiles, aircraft and unmanned vehicles (UAV/UGV). Ideally suited for embedded applications, its small size, lightweight design and low power consumption (4 watts) provide advantages for gimbaled or flight control applications requiring a small form factor demonstrating these characteristics.
The MMQ50 IMU employs three of its patented GyroChip® rate sensors, a mature design which uses double-ended quartz tuning fork technology. These sensors are built on BEI SDID’s high volume MEMS automotive production line. BEI SDID is a world-leading supplier of MEMS rate sensors, having shipped over 9,000,000 to date – and currently producing in excess of 10,000 per day. Each rate gyro channel is mated with a military qualified and proven ASIC. The MMQ50 uses high performance low cost silicon MEMS accelerometers that offer outstanding performance and is adaptable to a wide variety of applications requiring guidance, navigation and control.
The MMQ50 IMU offers substantial performance for a very attractive price. It features a full six degree of freedom (6DoF) sensing capability in an extremely compact size. It has a volume less than 5 cubic inches and weight less than 5 ounces.
The IMU is powered by a +/- 8Vdc supplies. The internal microprocessor thermally compensates the inertial sensors to minimize thermal errors. The unit outputs a low voltage serial RS-644 digital signal data stream comprising angular velocities and linear accelerations about the three orthogonal axes. These are in delta velocity (DV) and delta theta (Dθ) format. The MMQ50 is now in production and available. For further information and detailed specifications, visit our web site at www.systron.com.
About The Company
BEI Systron Donner Inertial is an operating division of BEI Technologies, Inc., an established manufacturer of electronic sensors, motors, actuators and motion control products used for factory and office automation, medical equipment, military, aviation and space systems. In addition, sales to manufacturers of transportation equipment including automobiles, trucks and off-road equipment have become a significant addition to the Company's business in recent years. BEI’s micromachined quartz yaw rate sensors are being used in advanced vehicle stability control systems and a significant increase in the production of those sensors has been in progress from the middle of 1998 to 2003, except for a decrease in production in fiscal 2002 (October 1, 2001 – September 31, 2002) due to increased competition. BEI is currently transitioning to its next generation of automotive inertial quartz based sensor products, remotely mounted multi-sensor clusters with CAN bus and a multi rate sensor package suitable for incorporation into electronic systems modules. BEI also manufactures electronic steering wheel position sensors, seat-memory modules, throttle position sensors, pressure sensors, and other devices used in transportation systems.
