KVH CG-5100 IMU
The CG-5100 IMU from KVH Industries is a low drift, solid state, FOG-based commercial solution that offers versatility for critical sensing and GPS-integrated navigation applications. It combines KVH's highly precise fiber optic gyroscopes with MEMS accelerometers that have been proven in demanding industrial environments.
Description
Overview
The versatile KVH CG-5100 Inertial Measurement Unit (IMU) combines proprietary technologies – highly accurate fiber optic gyro (FOG)-based sensors coupled with industry proven MEMS accelerometers – all within a compact single enclosure, providing reliability and long-term compliance to customer specifications. Through its seamless integration of these two highly reliable navigation components, the CG-5100 provides a ground-breaking low cost, small form factor solution for inertial measurement.
The KVH sensor engine of FOGs and accelerometers creates a flexible and efficient IMU, a high performance motion sensing package ideally suited for critical sensing applications and GPS integrated navigation systems. This strap-down inertial subsystem offers outstanding reliability and accurate 6-degrees-of-freedom measurement. The CG-5100 achieves its excellent performance by employing proprietary algorithms to a fully digital gyro sensor output, enabling the system to characterize and correct for the effects of temperature and misalignment. The CG-5100 also affords the end user with a convenient and easy to adapt output in a fully digital RS-232/RS-422 format.
