Spatial FOG


 
General 
Product Name:Spatial FOG
Product Description:Spatial FOG is a ruggedized 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 an RTK GNSS receiver.
