FOG-based high-performance inertial navigation system
0,01° heading and attitude accuracy
0,1 % DT position accuracy
with DVL compatibility
PHINS is an inertial navigation system providing position, true heading, attitude, speed, depth and heave. Its high accuracy inertial measurement unit is based on iXBlue’s fiber-optic gyroscope technology coupled with an embedded digital signal processor that runs an advanced Kalman filter. PHINS is compatible with doppler velocity log (DVL) and is overlooked for unmanned underwater vehicles (UAV).
