Spatial FOG Dual | Advanced Navigation

Spatial FOG Dual is an industry-proven GNSS/INS and AHRS. It combines high accuracy fibre optic gyroscopes, accelerometers, magnetometers, and a pressure sensor with a dual antenna RTK GNSS receiver. These are coupled in an AI-based fusion algorithm to deliver accurate and reliable navigation data. Spatial FOG Dual is compatible with our post-processing kinematic (PPK) software Kinematica.

Features

High-Accuracy FOG

High-Accuracy FOG

Spatial FOG contains the EMCORE TAC-450 fiber optic gyro IMU, which provides very accurate inertial data, beyond the best MEMS technology available. This allows Spatial FOG to achieve very high accuracies and dead reckon without GNSS for extended periods of time. Despite the high accuracy FOG IMU, Spatial FOG has a very competitive price tag that is lower than many MEMS systems on the market.
AI Based

AI Navigation Algorithm

Spatial FOG features Advanced Navigation's revolutionary AI neural network sensor fusion algorithm. This provides accuracy of up to 10 times that of a traditional kalman filter. It was designed for control applications and has a high level of health monitoring and instability prevention to ensure stable and reliable data.

Trusted Reliability

Reliability

Spatial FOG has been designed from the ground up for mission critical control applications where reliability is very important. It is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance in mind. The hardware is designed and manufactured to mil standards.

Dual Antenna | RTK GNSS

Dual Antenna RTK GNSS

Spatial FOG Dual contains a dual frequency RTK GNSS receiver that provides up to 10 mm accuracy positioning and supports all of the current and future satellite navigation systems, including GPS, GLONASS, Galileo, and BeiDou. Dual antenna heading provides high accuracy heading that is not impacted by magnetic interference and has no motion requirements.

Protocols Interfaces

Peripherals

Spatial FOG Dual features two general purpose input output pins and two auxiliary RS232/RS422 ports that support an extensive number of peripherals. Including odometer based input for ground vehicles, DVLs and USBLs for underwater navigation, NMEA input/output and more.
