Economical, compact and highly accurate vertical gyro modules offers great performance and accuracy

MEMSIC has announced the addition of the VG380 to its portfolio of inertial modules. These new vertical gyros provide 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 device is offered in two package/interface options, VG380SA and VG380ZA. The VG380SA is a 41mm x 48mm x 22mm 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 24mm x 37mm x 9.5mm package, and an SPI/UART interface for convenient integration into an end user system. The VG380 is the latest addition to a family of interchangeable and compatible modules offering different levels of functionality and performance. The IMU380 is a six or nine DOF inertial measurement unit which provides X, Y and Z acceleration, angular rate, and magnetic field (fully calibrated over temperature); the device 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. The device is designed for attitude determination and platform stabilization in applications such as unmanned aerial vehicles, satellite antenna tracking, precision agriculture, surveying instruments, and construction equipment, where size, performance, and cost are critical. John Newton, MEMSIC’s VP and GM for the Systems Business Unit, commented “We are excited about the addition of the VG380 to our growing line of inertial modules. MEMSIC was the first company to bring to market a MEMS-based FAA-certified AHRS, and we are continuing to pursue our strategy of leveraging MEMS sensors to reduce the size and cost of these inertial modules.”
