All of these versions are available in both the embedded and the standalone packages described above. 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. The VG380 is the latest addition to a family of interchangeable and compatible modules offering different levels of functionality and performance. The VG380ZA is designed for OEM/embedded applications, offering a much smaller 24x37x9.5 millimeter package, and an SPI/UART interface for convenient integration into an end user system. The VG380SA is a 41x48x22 millimeter 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 VG380 is offered in two package/interface options, VG380SA and VG380ZA. The static and dynamic accuracy is specified at +/-0.2 and +/-1.0 degrees (respectively) over the -40C to +85C temperature range. These new vertical gyros are designed to provide highly accurate pitch and roll (with respect to gravity), in both static and dynamic conditions. MEMSIC Inc., with headquarters in Andover, Massachusetts, recently announced the addition of the VG380 to its portfolio of inertial modules.
