Phins Subsea
FOG-based high-performance subsea inertial navigation system for deep water
Phins Subsea is a subsea inertial navigation system providing position, true heading, attitude, speed, depth and heave. Its high-accuracy inertial measurement unit is coupled with an embedded digital signal processor that runs an advanced Kalman filter. Phins Subsea can be pre-assembled and precalibrated with a doppler velocity log sensor, making the system easy to install and ready to use for more precise navigation.
