Designed for Critical Control Applications
Designed for demanding navigation and control applications, the GEO-FOG 3D has performance monitoring and instability protections to ensure stable and reliable data. The rugged KVH GEO-FOG 3D INS is designed and tested to ensure that the hardware is both secure and reliable. It is protected from reverse polarity, overvoltage, surges, static and short circuits on all external surfaces. The embedded GNSS includes Receiver Autonomous Integrity Monitoring (RAIM) to assess the integrity of satellite signals. The system also contains a backup MEMS IMU providing seamless inertial data collection for redundancy and backup purposes.
Embedded RTK GNSS Receiver & Integrated North-seeking Gyrocompass
The KVH GEO-FOG 3D contains a triple frequency GNSS receiver providing 8 mm positioning accuracy. It supports all of the current and future satellite navigation systems including GPS, GLONASS, GALILEO, and BeiDou. It also offers data rates up to 1000 Hz, and data can be output over a high-speed RS-422 interface or RS-232 interface. The GEO-FOG 3D features a north-seeking algorithm. This provides accurate heading as fast as 10 seconds after power-on from a hot start, and 10 minutes from a cold start. The north-seeking algorithm runs continuously while the INS is operating, and is unaffected by velocity or angular motion. This means the GEO-FOG 3D provides high accuracy heading in environments in which magnetometers and GPS-heading cannot be used.
