KVH's FOG page...
Through its seamless integration of two reliable navigation components – highly accurate KVH fiber optic gyros (FOGs) and industry-proven MEMS accelerometers – the CG-5100 offers a groundbreaking low-cost, small form factor solution for inertial measurement within a single, compact enclosure.
KVH’s CG-5100 is a low drift, solid state, FOG-based commercial off the shelf (COTS) solution ideally suited for critical sensing applications and GPS-integrated navigation programs. 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 combined digital gyro and accelerometer output, enabling the system to characterize and correct for the effects of temperature and misalignment. It also offers the end user a convenient and easy-to-adapt output in a fully digital, user-selectable RS-232/RS-422 format.
The CG-5100 is KVH’s second commercial single-enclosure measurement and navigation solution. For applications that need both GPS and FOG-based IMU capabilities, the CNS-5000 GPS/IMU is a perfect choice. The CNS-5000 combines a FOG-based IMU with NovAtel’s OEMV3 precision GPS receiver technology to optimize raw data and provide a highly reliable position, velocity, and attitude solution for applications like seaport management, surveying, and precision agriculture.
