VG800CA Datasheet

Powerful Solutions for a Better Life
VG800
LOW DRIFT MEMS VERTICAL GYRO
MEMSIC’s VG800CA establishes a new level of
performance for standalone “unaided” inertial
systems. The VG800CA combines advanced MEMS
rate gyro and accelerometer technologies to provide
a superior solution for measurement of dynamic
roll and pitch angles in demanding environments.
NEXT GENERATION
Features
• Advanced MEMS Sensors
• Low Drift < 3°/hr
• High Reliability, MTBF > 20,000 hrs
ROV/UUV Control
Antenna/Camera Stabilization
• Stabilized Roll/Pitch Angle Outputs
The VG800CA can be configured as a high performance IMU
for integrated navigation systems, or as a vertical gyro for
stabilization and control applications. Output data is available in
both analog and digital formats, and a VG700-compatible mode
is available for customers converting from the FOG-based VG700
to the MEMS-based VG800.
• Fully Compensated Angular Rate
and Linear Acceleration Outputs
• Digital (RS-232/RS-422) & Analog
Outputs
• VG700-Compatible Interface Option
Applications
• Unmanned Vehicle Control (ROV/UUV)
• Antenna/Camera Stabilization
• Flight Data Acquisition
10-32VDC @ <400mA
