ABSTRACT:
Improved navigational apparatus which interfaces between a Loran C receiver and a ship's auto pilot is disclosed. Output information from the Loran receiver is taken from a standard NMEA jack and is input to the inventive apparatus. Steer and steer correction signals output from the inventive apparatus are input to the auto pilot. The receiver's serial output data is converted to a parallel output and temporarily stored or held by a data latch. A timer releases the data to a logic circuit which supplies steer correction signals to the auto pilot. The timer, in conjunction with the logic circuit, inputs the steer signals at predetermined time spaced intervals to prevent circling of the ship. A data subtractor in conjunction with the timer reduces the ship's rate of return to the predetermined course setting.
