In support of the requirement to improve navigational accuracy for deep water bathymetric surveys, the United States Navy has developed and is presently using a sophisticated deep water integrated navigation system called IDWNS. The system design is described including the hardware components and system software. This navigation system accepts input data from doppler sonar, gyro compass, satellite, LORAN C and bottom transponder sensors and incorporates a KALMAN filter to provide a continuous indication of ship's position. IDWNS computational control unit is a HP 21XX series computer with 32 K memory augmented by executive function software for I/O of all computer peripherals/navigation sensors and mathematical programs to calculate ship positions and provide dead reckoning.
