Spatial FOG Dual
The Spatial FOG Dual is a dual-antenna moving baseline RTK GNSS INS/AHRS solution. Featuring a cutting-edge fiber optic gyro IMU and a triple-frequency all-constellation Trimble RTK GNSS receiver, it provides accuracy of up to 8mm, and also supports the Omnistar service for even higher performance.
The versatile sensor is ideal for a wide range of marine and maritime applications, especially those requiring enhanced heading performance or facing high levels of magnetic interference. It can be easily interfaced to third-party peripherals such as DVLs and USBLs, NMEA sources, and more.
