VG440 Datasheet

VG440
MEMS-Based Vertical Gyro
VG440
DESCRIPTION
The Crossbow 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, including platform stabilization,
unmanned vehicle control and automotive testing.
