The VG440 is a high-reliability low power strapdown vertical gyroscope that provides roll, pitch and yaw measurement data in both static and dynamic environments. The VG440 can accept external GPS aiding inputs for optimized performance, and is available in standard and high range sensor configurations. The VG440 combines highly-reliable MEMS gyros and accelerometers with high-speed DSP electronics to provide a fully stabilized vertical gyroscope in a small and rugged environmentally-sealed enclosure. The VG440 provides consistent performance in challenging operating environments and is user-configurable for a wide variety of applications.

For customers wishing to use the VG440 in analog data acquisition systems, MEMSIC offers the NAV-DAC440 analog interface adapter. The NAV-DAC440 converts the VG440 serial digital data to 9-channel BNC analog outputs.
