AUV inertial navigation system Spatial FOG Dual

for ROVsGNSShigh-accuracy

Spatial FOG Dual is a ruggedised GPS aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration and orientation under the most demanding conditions. It combines ultra high accuracy fibre optic gyroscopes, accelerometers, magnetometers and a pressure sensor with a dual antenna RTK GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver accurate and reliable navigation and orientation. Performance - 0.01 ° Roll and Pitch - 0.01 ° Heading - 8 mm RTK Positioning - 0.05 °/HR FOG Gyroscope - Heave : 2 % or 0.02 m (whichever is greater) Key Features - Dual Antenna Heading - L1/L2 RTK/PPK - Hot Start Time : 2 seconds - Rapid North Seeking : 10 s from hot start - Low size, Weight and Power
