High-accuracy MEMS vertical gyro modules for platform stabilization
Memsic presents the devices as providing highly accurate pitch and roll (with respect to gravity), in both static and dynamic conditions, at a very attractive size and price points. The static and dynamic accuracy is specified at ±0.2 and ±1.0 degrees (respectively) over the -40C to +85C temperature range.
The VG380 comes in two package/interface options, VG380SA and VG380ZA. The VG380SA is a 41 x 48 x 22 mm module designed for standalone applications, including built in power conditioning (compatible with power supplies from 9 – 32V), and with RS-232 / RS-422 interface.
The VG380ZA is designed for OEM/embedded applications, offering a much smaller 24 x 37 x 9.5 mm package, and an SPI/UART interface for convenient integration into an end user system.
The VG380 is part of a family of interchangeable and compatible modules offering different levels of functionality and performance. The IMU380 is a 6 or 9 DoF (Degrees-of-Freedom) inertial measurement unit which provides X, Y and Z acceleration, angular rate, and magnetic field (fully calibrated over temperature); the VG380 now adds the algorithms to deliver accurate pitch and roll information; and the AHRS380 (Attitude-Heading-Reference-System) adds additional algorithms to compute both attitude and heading. All of these versions are available in both the embedded and the standalone packages described above.
Memsic says it was the first company to bring to market a MEMS-based FAA-certified AHRS [Attitude-Heading-Reference-System], and they company is continuing to pursue a strategy of further developing MEMS sensors to reduce the size and cost of these inertial modules.
VG380ZA and VG380SA pricing starts at $353 (Qty 100). There is an evaluation kit (EVAL-KIT DMU380ZA) with a USB PC-connection and GUI to speed the evaluation and prototyping phases.
